Alternate Angles - GCSE Maths - Steps, Examples & Worksheet

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° 180° goes with "S" for … WebSal constructs CF parallel to AB not equal to AB. We know that BD is the angle bisector of angle ABC which means angle ABD = angle CBD. Now, CF is parallel to AB and the transversal is BF.

Supplementary angles are angles that add up to 180˚. The sum of angles in a triangle is 180˚. An exterior angle of a triangle is equal to the sum of the two opposite interior angles. The sum of interior angles of a quadrilateral is 360˚.

WebAlternate interior angles are on opposite sides of the transversal and in between the two lines, with one of the angles formed using one line and the other formed using the other line. WebWe know that the sum of all the interior angles in this polygon is equal to 720°. The sum of all the angles of the given polygon is: ∠A + ∠B + ∠C + ∠D + ∠E + ∠F = (x - 60) + (x - 20) + 110 + 120 + 130 + (x - 40) = 3x+ 240 Now we set this sum equal to 720 and solve it for x. 3x+ 240 = 720 3x = 480 x = 480/3 = 160 Now, let us find ∠B.
