Geometry

Isosceles Triangle

• a triangle with at least two angles having the same measure

• a triangle with all sides of different lengths

• a triangle where all angles are equal

• a triangle with one angle greater than 90 degrees

Square

• a rectangle with all 4 sides equal (having the same length), and 4 square corners or right angles

• a shape with four equal sides and no right angles

• a polygon with four sides of different lengths

• a three-dimensional shape with six square faces

Angle

• the figure formed by 2 lines extending from the same point

• a measurement of the distance between two points

• a type of geometric shape with three sides

• the sum of the interior angles of a polygon

Scalene Triangle

• a triangle with no equal sides

• a triangle with two equal sides

• a triangle with all sides equal

• a triangle with one right angle

Intersecting lines

• lines that run parallel to each other

• lines that cross at one point

• lines that never meet

• lines that are perpendicular to each other

Non Polygons

• A shape that is flat and has straight sides

• A shape that is fully closed and has curves

• A shape that isn't flat, doesn't have straight sides, or isn't fully closed

• A shape that is a triangle or a square

Congruent

• "congruent" means two shapes or sides are exactly the same, the same size and shape, even if they are turned or flipped.

• "congruent" refers to shapes that are similar but not necessarily the same size.

• "congruent" indicates that two shapes have the same area but different dimensions.

• "congruent" means that two shapes are identical in color but not in size.

Quadrilaterals

• A closed shape with three straight sides and three corners.

• A closed shape with four straight sides and four corners.

• A closed shape with five straight sides and five corners.

• A closed shape with four curved sides.

Trapezoid

• a quadrilateral with no parallel sides

• a quadrilateral with two pairs of parallel sides

• a "special" quadrilateral with exactly one pair of parallel lines

• a quadrilateral with four equal sides

Parallelogram

• a polygon with exactly 4 sides and 2 sets of sides that will never meet (2 sets of parallel sides)

• a shape with three sides and three angles

• a polygon with four sides of equal length

• a figure with one pair of parallel sides and two non-parallel sides
