Can you figure out whether the converse of the consecutive interior angle theorem is true or not. A rectangle is a special parallelogram that has 4 right angles. Consecutive angles are supplementary If you start at any angle, and go around the parallelogram in either direction, each pair of angles you encounter always are supplementary - they add to 180°. 9 terms. Let ABCD be a parallelogram and AC as its diagonal. Consecutive angles in a parallelogram are supplementary (A + D = 180°). Hence, it is proved that any two adjacent or consecutive angles of a parallelogram are supplementary. The three different types of the parallelogram are: Square. x=30. The consecutive angles of the parallelogram ABCD are the angles. Therefore, it's a simple use of the properties of parallel lines to show that the consecutive angles are supplementary.. We have already proven that for the general case of parallel lines, a transversal line creates interior angels that sum up to 180°. A parallelogram is a quadrilateral which has two pairs of opposite sides parallel to each other. Similarly for the section 2 are $ (\angle \text E, \angle \text F)$ and $ (\angle \text G, \angle \text H)$ are the pair of consecutive angles. Problem 1 $$\angle Y = 40 ^{\circ}$$. Using the above as an example: If all sides of the parallelogram are equal then the shape we have is called a rhombus. Two consecutive angles of a parallelogram are in the ratio of 1:8.
