Complementary Angles Gcse Maths Steps Examples Worksheets Library

Complementary Angles Gcse Maths Steps Examples Worksheets Library The two angles are complementary and therefore equal 90°. 2 clearly identity which of the unknown angles the question is asking you to find the value of. find the angle that is not 17°. 3 solve the problem and give reasons where applicable. 4 clearly state the answer using angle terminology. Adding the angles together, we can form the expression. 70 90 = 160.70 90 = 160. 2 subtract the angle sum from 180 o180o. as the sum of angles on a straight line total 180 o, 180o, 180 − 160 = 20.180 −160 = 20. 3 form and solve the equation. here we have no equation to solve as the missing angle is 20 o.20o.

Complementary Angles Gcse Maths Steps Examples Worksheets Library Example 1: angles on a straight line. find angles a and b. identify which angle you need to find (label it if you need to). you need to find angles labelled a and b. 2 identify which angle rule s apply to the context and write them down (remember multiple rules may be needed).

Complementary angles vs supplementary angles. complementary angles and supplementary angles both involve pairs of angles that have specific relationships with each other. complementary angles. complementary angles are two angles that when added together, result in `90°`. they can either be adjacent or non adjacent. 40 degrees x = 90 degrees (the sum of the two complementary angles) x = 90 – 40 = 50 degrees. therefore, the measure of the other acute angle in the triangle is 50 degrees. example 3: the measure of one angle of a triangle is 30 degrees less than its complementary angle. find the measures of the two angles. solution:.
