Parallelogram: A quadrilateral with 2 pairs of parallel sides. Rectangle: A parallelogram with 4 right angles.

Rectangle

Parallelogram: A quadrilateral that has two pairs of parallel sides. Rhombus: A quadrilateral with four congruent sides; a rhombus is both a kite and a parallelogram. Rectangle: A quadrilateral with four right angles; a rectangle is a type of parallelogram.

A rhombus is a quadrilateral which has the following four properties:

• Opposite angles are equal.
• All sides are equal and, opposite sides are parallel to each other.
• Diagonals bisect each other perpendicularly.
• Sum of any two adjacent angles is 180°

360−3(90) , or 90 degrees. Since the resultant figure has 4 right angles, its opposite sides must be parallel, so it cannot be a trapezoid.

A 3-sides-equal trapezoid is an isosceles trapezoid having at least three congruent sides. Below is a picture of a 3-sides-equal trapezoid. In some dialects of English (e.g. British English), this figure is referred to as a 3-sides-equal trapezium.

Thus the right kite is a convex quadrilateral and has two opposite right angles. If there are exactly two right angles, each must be between sides of different lengths. All right kites are bicentric quadrilaterals (quadrilaterals with both a circumcircle and an incircle), since all kites have an incircle.

A trapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are called bases, and the other two sides are called legs. In other words, the lower base angles are congruent, and the upper base angles are also congruent.

Base Angles in Isosceles Trapezoids The two angles along the same base in an isosceles triangle will be congruent. Thus, this creates two pairs of congruent angles—one pair along each base. The base angles of an isosceles trapezoid are congruent.

The same shape and size, but we are allowed to flip, slide or turn. In this example the shapes are congruent (you only need to flip one over and move it a little). Angles are congruent when they are the same size (in degrees or radians). Sides are congruent when they are the same length.

a consistent state of behavior, meaning there is consistency between the goals, values, and attitudes projected and the actual behavior observed. In personality research, ideally, the way you think and feel should also be the way you behave.

It is rapport within oneself, or internal and external consistency, perceived by others as sincerity or certainty. Carl Rogers coined the term congruence to describe the match or fit between an individual’s inner feelings and outer display. The congruent person is genuine, real, integrated, whole, and transparent.

Congruent figures are two figures of the same size and shape that can be obtained from one another by rotating, reflecting, or sliding one of the figures. When two figures are congruent, they have the following properties: Corresponding angles have equal measure. Corresponding sides have equal length.

Mood congruence is the consistency between a person’s emotional state with the broader situations and circumstances being experienced by the persons at that time.
