Explanation
A triangle with angles 45°, 45°, 90° has two equal angles, making it isosceles. Since one angle is 90°, it's also right-angled. Combining these properties gives a right-angled isosceles triangle.
AI explanation
A triangle with two equal angles (45 and 45) has two equal sides, making it isosceles, and the third angle of 90 makes it right-angled — together that's a right-angled isosceles triangle.
