How to calculate unknown angles

WebThe 45°-45°-90° triangle, also referred to as an isosceles right triangle, since it has two sides of equal lengths, is a right triangle in which the sides corresponding to the angles, 45°-45°-90°, follow a ratio of 1:1:√ 2. Like the 30°-60°-90° triangle, knowing one side length allows you to determine the lengths of the other sides ...

WebSupplementary angles add up to 180°. - example: 60° & 120°. (added together, they form a straight line) Two facts: (1) 90° comes before 180° on the number line. (2) "C" comes before "S" in the alphabet. You can use this to help you remember! 90° goes with "C" for complementary. so complementary angles add up to 90°. WebThe sum of the measure of the three interior angles of a triangle is always 180 o.
