# CBSE Class 9 Maths Angle Sum Property Of A Triangle

## Videos

- In a triangle ABC, if angle A + angle B = 65 and angle B + angle C = 140 , then the measure of angle B is (a) 40 (b) 25 c) 115 (d) 60
- one exterior angle of a triangle is 110 degree and one ko interior opposite angle is 30 degree find the remaining angles of the triangle
- What is angle sum property
- In the given figure, AB||CD. Find the value of x.
- answer to all question
- Please answer this question
- Can a triangle have
(i) Two right angles? (ii) All angles less than 60
^{o}? (iii) All angles equal to 60^{o}? (iv)Two acute angles? Justify your statement in each case. - If the bisectors of B and C of triangle of a ABC intersect at O, then prove that BOC = 90
^{o}+ . - The sides AB and AC of a triangle are produced to D and E respectively. The bisectors of CBD and BCE meet at O. If A = 40
^{o}, find BOC. - In triangle ABC, if A + B = 108
^{o}and B +C = 130^{o}, find A, B and. C
