Question

Choose the correct answer from the given alternatives:
In a triangle ABC, ∠B = ∠C =45°, then the triangle is .............
A. right triangle
B. acute angled triangle
C. obtuse angle triangle
D. equilateral triangle

Answer 1

B.acute angled triangle

Answer 2

Answer:

Right Triangle

Step-by-step explanation:

Given:∠B = ∠C =45°

Now Angle Sum Property of triangle states that he sum of all angle of a triangle is 180 degree.

So, 2 angles are already given hence,

sum= 45(angleb)+45(anglec)

= 90

Angle a= 180-90

= 90 degree

Hence one angle is 90 degree and the other 2 angles are equal hence it is an isosceles right angled triangle.
