give me an example for all of them

area – the size of the surface of the two-dimensional plane of a regular quadrilateral

congruent – equal, identical

triangle – a three-sided polygon

perimeter – the distance around the outside of a closed two-dimensional shape

parallel – two lines that are always the same distance apart and will never meet

volume – the amount of space occupied by a three-dimensional object

equilateral – a polygon with all sides equal in length

radius – a line segment from the center of a circle or sphere to any point on its circumference

acute angle – an angle that measures less than 90 degrees

right triangle – a triangle with one angle measuring 90 degrees

complementary angles – two angles that add up to 90 degrees when combined

slope – the steepness of a line on a graph or in a coordinate system

only the two of them

Sure!

Area: The area of a rectangle can be calculated by multiplying its length by its width. For example, if a rectangle has a length of 5 units and a width of 8 units, the area would be 5 x 8 = 40 square units.

Congruent: Two triangles are congruent if all their corresponding sides and angles are equal. For example, if two triangles have sides of lengths 6, 8, and 10 units respectively, and all their corresponding angles are equal, then they are congruent.
