Five geometric theorems
WebA few important theorems are: Theorem 1: Equal chords of a circle subtend equal angles, at the centre of the circle. Converse of Theorem 1: If two angles subtended at the … Webangles on the same side of the transversal are supplementary, then the lines are parallel. The sum of the degree measures of the same-side interior angles is 180°. Vertical Angles Theorem If two angles are vertical angles, then they have equal measures. The vertical angles have equal degree measures. There are two pairs of vertical angles.

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°. Example 2: Tim wants to construct a triangle with the lengths of sides 5 cm, 4 cm, and 9 cm.
