## Important Questions for CBSE Class 9 Mathematics Quadrilaterals

Objective To verify that in a triangle, the line joining the mid-points of any two sides is parallel to the third side and half of it by paper folding and pasting.

Materials Required Glazed papers, a pair of scissors, pencil, eraser, gluestick, white sheet. By paper folding we observe that, in fig iv F, the mid point of BC coincides with D. Result Hence, it is verified that the line joining the mid-points of two sides of a triangle is parallel to third side and half of it. Learning Outcome Line segment joining the mid-points of any two sides of a triangle is parallel to the third side and is equal to half of it.

This is true for all types of triangles like acute-angled triangle, obtuse-angled triangle and right-angled triangle. Activity Time Students can verify this theorem in different triangles, e. Question 1. State the mid-point theorem.

Answer: The line drawn through the mid-point of one side of a triangle and parallel to another side of the triangle, bisects the third side of the triangle. Question 2. What is the area of a triangle? Question 3. Name the different triangles on the basis of its sides. Answer: Equilateral triangle, scalene triangle, isosceles triangle. Question 4. Name the different triangles on the basis of its angles.

Answer: Acute angled triangle, obtuse angled triangle and right angled triangle. Question 5. Is mid-point theorem applicable in any type of triangle? Answer: Yes. Question 6. In a triangle, the line drawn through the mid-point of one side is parallel to another side, what is the ratio of parallel line to the third side? Answer: Question 7. In a triangle, the line drawn through the mid-points of two sides, then what will be the relation between the line and the third side?

Answer: Line will be parallel to the third side. Question 8. In a right-triangle, mid-points of corresponding sides are joined, the resulting triangle will be: i an acute angled triangle ii an obtuse angled triangle iii a right-angled triangle iv none of these.

The figure so obtained ACBQ is a i parallelogram ii rectanlge iii trapezium iv none of these. Question 9. Join P, Q and R. Question Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.

CBSE Class 9 Maths Lab Manual — Mid-point Theorem Objective To verify that in a triangle, the line joining the mid-points of any two sides is parallel to the third side and half of it by paper folding and pasting.

Prerequisite Knowledge Concept of angles, triangles and mid-points. Concept of corresponding angles: If a transversal cuts two straight lines such that their corresponding angles are equal, then the lines are parallel. Find mid-points of the two sides say AB and AC of a triangle by paper folding.

Draw horizontal line DE. Similarly find mid-point of side BC and name it F as shown in fig. Paste this cut out of triangle ADE [fig.

Viva Voce Question 1. In a right-triangle, mid-points of corresponding sides are joined, the resulting triangle will be: i an acute angled triangle ii an obtuse angled triangle iii a right-angled triangle iv none of these Question 7.

The figure so obtained ACBQ is a i parallelogram ii rectanlge iii trapezium iv none of these Question 9. Comments Sabse ghatiya answers, worlds worst answer. Leave a Reply Cancel reply Your email address will not be published.

This is true for all types of triangles like acute-angled triangle, obtuse-angled triangle and right-angled triangle.

Write down your observations. Prove that the line joining the mid-points of two sides of a triangle is parallel to the third side and equal to half the length of the third side. We conclude that the line joining the two mid-points of two sides of a triangle is parallel to the third side. We conclude that the line joining the mid-point of two sides of a triangle is equal to half the length of the third side. The converse of this theorem states: If a line is drawn through the mid-point of a side of a triangle parallel to the second side, it will bisect the third side.

## MID POINT THEOREM

Suppose that you join D and E:. In the simulation below, drag the vertices of the triangle to see the Midpoint Theorem in action. By the ASA criterion, the two triangles are congruent. This implies that BCFD is a parallelogram. This completes our proof.

In geometry , the midpoint is the middle point of a line segment. It is equidistant from both endpoints, and it is the centroid both of the segment and of the endpoints. It bisects the segment. Given two points of interest, finding the midpoint of the line segment they determine can be accomplished by a compass and straightedge construction.

- Меня осенило. Здесь шестнадцать групп по четыре знака в каждой. - О, ради Бога, - пробурчал себе под нос Джабба.

Боже всевышний. Похоже, мне не уйти. Асфальт впереди становился светлее и ярче. Такси приближалось, и свет его фар бросал на дорогу таинственные тени.

Стратмор кивнул: - Совершенно. - Повисла продолжительная пауза. - Прости, что я тебе лгал. Попытка переделать Цифровую крепость - дело серьезное и хлопотное. Я не хотел тебя впутывать. - Я… понимаю, - тихо сказала она, все еще находясь под впечатлением его блистательного замысла. - Вы довольно искусный лжец.

Бринкерхофф проследовал за Мидж в ее кабинет. Она села и начала, подобно пианисту-виртуозу, перебирать клавиши Большого Брата. Бринкерхофф посмотрел на мониторы, занимавшие едва ли не всю стену перед ее столом. На каждом из них красовалась печать АНБ. - Хочешь посмотреть, чем занимаются люди в шифровалке? - спросил он, заметно нервничая. - Вовсе нет, - ответила Мидж. - Хотела бы, но шифровалка недоступна взору Большого Брата.

Да нет, - замялся. - Я просто… - Сьюзан Флетчер. - Женщина улыбнулась и протянула ему тонкую изящную руку. - Дэвид Беккер. - Он пожал ее руку.
