Answer:
45+45+90
This triangle would be a isosceles triangle.
Step-by-step explanation:
All triangles have three angles. These angles always add up to 180 degree. So 45+45 would be 90, 90+90 = 180.
This would be a scalene triangle if all the angles had different numbers to equal 180.
It is an isosceles if the triangle has two angles that are the same and one different.
It is an equilateral if all the angles are the same to equal 180.
Two of the angles are the same (45, 45) so this would be defined as an isosceles triangle.
Hope this helps you! (:
