Answer:
C. Right isosceles
Step-by-step explanation:
In Acute scalene triangle, all angles are acute ( less than 90 degrees ) and different,
In Right scalene triangle, two angles are acute and different, while, the third angle is of 90°.
In Right isosceles triangle, two angles are acute and equal, while, the third angle is of 90°.
In Acute isosceles, all angles are acute in which any two angles are equal.
Now, given,
The two angle of the triangles are 45° and 45°,
Let x be the third angle,
⇒ x + 45° + 45° = 180°
⇒ x + 90° = 180°
⇒ x = 90°
Hence, the angles of given triangle are 45°, 45° and 90°,
By the above definitions,
It is clear that, given triangle is right isosceles.
Option C is correct.
