A triangle has angles of 100 degrees, 40 degrees and 40 degrees. Select all the statements that are true about this triangle.

Объяснение

The two angles of 40 degrees face two sides of the same length, so on the side axis this triangle is isosceles and it does have a matching pair of sides. The name for a triangle with three different sides is ruled out for that very reason, and the 100 degree angle is plainly larger than a right angle.
