Is it true that Some parallelograms are rectangles?
A parallelogram is a four sided figure. that has congruent angles and all sides are parallel
What is a description of a parallelogram?
A parallelogram is a quadrilateral (4-sided figure) with both pairs of opposite sides parallel. That's usually the primary definition. There are properties common to all parallelograms: opposite sides are congruent, opposite angles are congruent, and diagonals bisect each other. Other special parallelograms have additional properties. A rectangle is a parallelogram with four right angles and its diagonals are congruent. A rhombus is a parallelogram with four congruent sides. Its diagonals are perpendicular and each diagonal bisects two angles of the rhombus. A square is a parallelogram as well. It has four right angles and four congruent sides, so it is also a rectangle and a rhombus. How's that for confusing???
What marks used on a figure to indicate congruent angles?
marks used on a figure to indicate congruent
Is this false if a figure has four congruent angles then its a square?
Yes, it is false. It need not be a square.
What is a 2 dimensional figure with 4 right angles and 4 congruent sides?
A square.

Does a quadrilaters have exactly three congruent angles?
Not sure what a "quadrilaters" is. A quadrilateral is a plane (2-dimensional) figure with four straight sides. It can have all four angles different. It can have two congruent angles (kite), 3 congruent angles (no specific name), 2 pair of two congruent angles (parallelogram/rhombus), or four congruent angles (rectangle/square).
Does a quadrilateral have congruent angles?
A quadrilateral is a plane figure with four straight sides and does not necessarily have any congruent angles. Some quadrilaterals such as, squares, rectangles, rhombuses, and parallelograms do have congruent angles.
Is a closed plane figure with 4 congruent sides and 0 right angles?
That's a rhombus ... a special type of parallelogram.

How can you tell if it is a parallelogram?
A parallelogram is a quadrilateral (four-sided figure) in which both pairs of opposite sides are parallel. You can check for that, specifically. As an alternative, you can check for any of the following conditions: * Opposite angles are congruent * Opposite sides are congruent
Is a pentagon a parallelogram?
No, a parallelogram is 4 sided with each 2 sides being parallel to one another. The opposite angles in a parallelogram are congruent. A pentagon is a 5 sided figure with each angle being the same.
How can a similar figure not be congruent?
if the angles of a figure are the same but the sides aren't, it is similiar. Congruent is angles and sides exactly the same
What figure has opposite sides congruent?
A parallelogram has two sets of congruent parallel sides.
What is the difference between a similar figure and a congruent figure?
A similar figure has the same interior angles as a congruent figure but its sides are in proportion to a congruent figure.
Are corresponding angles of similar figure always congruent?
Yes, they are.
