WebProperties of Equality: Addition Property If a = b and c = d, then a + c = b + d. Subtraction Property If a = b and c = d, then a – c = b – d. Multiplication Property If a = b, then ca = cb. Division Property If a = b and c ≠ 0, then a/c = b/c. Substitution Property If a = b, then either a or b may be substituted for the other in any equation (or inequality) WebSum of the measures of two angles = 75° + 60° = 135°. Using the properties of a triangle, we know that the sum of all three angles of triangle = 180°. Therefore, the measure of the third angle = 180° - 135° = 45°. … somberwald beastmaster
