Question

সমকোণী সমদ্বিবাহু ত্রিভূজের তিনটি কোনের পরিমাণ কত?

Answer 1

180 degrees

Since the two sides are equal which makes the corresponding angle congruent. Thus, in an isosceles right triangle two sides are congruent and the corresponding angles will be 45 degree each which sums to 90 degree. So the sum of three angles of the triangle will be 180 degrees.
