In a right triangle, the sum of the two non-right angles is...?
In a right-angled triangle, there is one angle that equals 90 degrees, and the other two angles sum up to 180 degrees (sum of angles in a triangle)
Therefore, the sum of the two non-right angles is 90 degrees
90 degrees
Look at the angles shown in the figure below.
What is their relationship?
\( \)
Because every triangle's angles must sum to 180°. Since one angle is already 90°, the remaining two must add up to to complete the triangle.
Yes! If both non-right angles are equal, each would be 45°. This creates a special right triangle called a 45-45-90 triangle or isosceles right triangle.
Simply subtract it from 90°! For example, if one angle is 30°, the other must be . The two non-right angles are complementary.
Absolutely! Every right triangle, no matter its size or shape, follows this rule. The right angle is always 90°, so the other two always sum to 90°.
Complementary angles add to 90° (like the non-right angles in a right triangle). Supplementary angles add to 180°. Remember: Complementary = Corner (90°)!
