WebJul 8, 2024 · A right triangle will have two acute angles that add up to 90° because the three angles of any triangle always add up to 180°. A right angle equals 90°, so the remaining two angles of a right triangle are complementary, meaning their sum is 90°. Web3 years ago. Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. Note that in these definitions, it does not matter whether or not the angles are adjacent; only their measures matter. For …

See answer (1) Copy. All triangles have a total of 180 degrees. The internal angles of any triangle add up to 180 degrees. Therefore, a RIGHT triangle's angle's added together equal 180 degrees. The Right Angle = 90 degrees + the other 2 angles total 90 degrees, making the total number of degrees in a Right Angle Triangle = … headpiece buff classic wowWebExample 2: Find the fourth angle of the right trapezium if one of the given angles is 60°. Solution: As we know, in a right trapezium, there are 2 right angles and the sum of all the interior angles in a trapezium is always 360°. So, if one of the given angles is 60°, let the missing angle be x°. The fourth angle can be calculated as x° + 90° + 90° + 60° = 360°. headpiece artWebA straight angle is 180 degrees. The angles W and X form a straight line, added together together they measure 180 degrees. They are also know as Adjacent Angles. Adjacent Angles add up to 180 degrees. Adjacent Angles are also. ∠ Y and ∠ Z, ∠ W and ∠ Y. ∠ X and ∠ Z.
