Question: If an angle measures 45° and is part of a right triangle, what is the measure of the other non-right angle?
Options:
35°
45°
55°
60°
Correct Answer: 45°
Solution:
In a right triangle, the sum of the angles is 180°. Therefore, 90° - 45° = 45°.

Questions & Step-by-Step Solutions
If an angle measures 45° and is part of a right triangle, what is the measure of the other non-right angle?
Triangle Angle Sum – In any triangle, the sum of the interior angles is always 180°. In a right triangle, one angle is 90°, so the other two angles must sum to 90°.
Properties of Right Triangles – In a right triangle, if one angle is known, the other non-right angle can be easily calculated using the angle sum property.
