What is a parallelogram with four angles?

What is a parallelogram with four angles?

A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals.

What are the opposite angles of a parallelogram called?

Opposite angles of a parallelogram are equal (or congruent) Consecutive angles are supplementary angles to each other (that means they add up to 180 degrees)

What is a parallelogram with 4 equal sides and equal opposite angles?

Rhombus – A parallelogram with four sides of equal length. Square – A parallelogram with four sides of equal length and angles of equal size (right angles).

Does parallelogram have all equal angles?

The important properties of parallelograms to know are: Opposite sides of parallelogram are equal (AB = DC). Opposite angles of parallelogram are equal (D = B). Consecutive angles in a parallelogram are supplementary (A + D = 180°). If one angle is 90 degrees, then all other angles are also 90 degrees. The diagonals of a parallelogram bisect each other in two equal halves.

What do all angles of a parallelogram equal up to?

Hence, it is proved that any two adjacent or consecutive angles of a parallelogram are supplementary. From the above theorem, it can be derived that if one angle of a parallelogram is equal to 90 degrees , then all four angles are equal to 90 degrees.

What is the total angles in a parallelogram?

The sum of angles of a Parallelogram equals 360 degrees . For the Rectangle or Square the sum total of four corners, each a 90 degree angle, give us 360 degrees. Click to see full answer Accordingly, does a parallelogram have 4 90 degree angles?

Are adjacent angles in a parallelogram are supplementary?

Adjacent angles in a parallelogram are always supplementary. Supplementary means the angles have a sum of 180 degrees. So if your first angle is 40 degrees the next angle would be 140 degrees. Rectangles are a subset of parallelograms .
