science space and astronomy# How do you find the angles in a parallelogram?

Last Updated: 3rd January, 2020

**Properties of parallelograms**

- Opposite sides are congruent (AB = DC).
- Opposite angels are congruent (D = B).
- Consecutive
**angles**are supplementary (A + D =180°). - If one
**angle**is right, then all**angles**areright. - The diagonals of a
**parallelogram**bisect each other. - Each diagonal of a
**parallelogram**separates it into twocongruent triangles.

Also to know is, what is the total of angles in a parallelogram?

**Parallelogram**. A **Parallelogram** is a flatshape with opposite sides parallel and equal in length.**Angles** "a" and "b" add up to 180°, so they aresupplementary **angles**. NOTE: Squares, Rectangles andRhombuses are all **Parallelograms**!

One may also ask, how do you find the measurement of a parallelogram? Opposite sides are equal in **length** and oppositeangles are equal in **measure**. To **find** the area of a**parallelogram**, multiply the base by the height. The formulais: A = B * H where B is the base, H is the height, and * meansmultiply.

Also asked, do all the angles in a parallelogram add up to 360?

Its four interior **angles add** to **360**°and any two adjacent **angles** are supplementary, meaning they**add** to 180° . Opposite (non-adjacent) **angles** arecongruent. The two diagonals of a **parallelogram** bisect eachother.

Are trapezoids parallelograms?

Some define a **trapezoid** as a quadrilateral havingonly one pair of parallel sides (the exclusive definition), therebyexcluding **parallelograms**. Under the inclusive definition,all **parallelograms** (including rhombuses, rectangles andsquares) **are trapezoids**.
