Question

16. Which of the following pairs of triangles are congruent?
i) A ABC : AB = 10cm, ZA = 40°, ZB = 55°
AXYZ : XY = 10cm, 2Y = 40°, ZZ = 85°
ii) APQR: PR = 5cm, P = 37°, ZR = 64°
ADEF: DE = 5cm, D = 37°, ZF = 64°​

Answer 1

Answer: The angle of E is  

Given:

It is given that triangle ABC congruent it triangle FDE and AB = 5cm , angle B is  and angle A is  

To find:

Then find the value of angle E

Solution:

In a triangle abc, sum of angles of a triangle = 180 deg

= 180

80 + 40 + = 180

Since the triangles are congruent ABC = FDE

So, the angle of C is equal to E.

Result:

The angle of E is  60
