Question 1

The ratio of base angle and vertical angle of an isosceles triangle (whose base angles are equal) is 2:5. Find the vertical angle.

Question 2

In the given figure, BP = DE = 8 cm and

What is the length of AC?

Question 3

In the diagram, M is the midpoint of YZ, XMZ = 32°, and XYZ = 16°. The measure of XZY is:

Question 4

In a ΔABC, the bisector of B intersect side AC at D. If AB = 7 cm, BC = 8 cm and AC = 12 cm, then find the length of AD. 

Question 5

In ΔABC, AB = AC. IfA is twice the sum of other two angles of the triangle then the measure of  is:

Question 6

In Δ PQR, S and T are mid-points of PQ and PR, respectively. If QPR = 75° and PRQ = 40°, then TSQ is:

Question 7

In ∆ABC, A = 58° and O is the orthocentre of the triangle (BO and CO meet AC and AB at E and F respectively when produced). If the bisectors of OBC and OCB meet at P, then the measure of BPC is:

Question 8

ΔABC and ΔPQR are similar to each other. If perimeter of ΔABC = 60 cm and perimeter of ΔPQR = 82 cm. If l(AB) = 8 cm, find the l(PQ) = ?

Question 9

Internal bisectors of angles and of a triangle ABC meet at O. If , then the value of is

Question 10

In ∆ABC A = 90o, M is the midpoint of BC and D is a point on BC such that AD BC. If AB = 7 cm and AC = 24 cm, then AD : AM is equal to :
