Right angle definition geometry simple

Web"h" is the height (measured at right angles to the base) Area = ½ × b × h The formula works for all triangles. Note: a simpler way of writing the formula is bh/2 Example: What is the area of this triangle? (Note: 12 is the height, not the length of the left-hand side) Height = h = 12 Base = b = 20 Area = ½ × b × h = ½ × 20 × 12 = 120 When two straight lines intersect each other at 90˚ or are perpendicular to each other at the intersection, they form the right angle.

WebComplementary Angles. In geometry, complementary angles are defined as two angles whose sum is 90 degrees. In other words, two angles that add up to 90 degrees are known as complementary angles. For example, if angle A is 20 degrees, then its complement angle B would be 70 degrees because 20 degrees + 70 degrees = 90 degrees.
