Question

What type of triangle is a 45-45-90 triangle?
select all that apply.
1. obtuse
2. acute
3. right
4. scalene
5. isosceles

Answer 1

3. Right
5. Isosceles

Isosceles triangles have 2 sides measuring the same length and a right triangle contains a 90 degree angle

Answer 2

The answers are 3. right, and 5. isosceles. It is a right triangle because any triangle with a 90 degree angle is a right triangle, and it is isosceles because its two other angles, 45 and 45 degrees, are equal, meaning that their legs are the equal length as well.
