Question

What type of triangle is given? (Note: The red hash marks denote the congruent sides. The small square represents a right angle.)a.) Acute Equilateral Triangleb.) Right Isosceles Trianglec.) Obtuse Scalene Triangle

Answer 1

An Isosceles Right Triangle is a right triangle that consist of two equal length legs.

Thus, in an isosceles right triangle, two legs and two acute angles are congruent.

Since it is a right triangle, the angle between the two legs would be 90 degrees, and the legs would be perpendicular to each other.

with these said above, the diagram is a Right Isosceles Triamgle.

therefore, option B is the correct answer.
