Perimeter:
The perimeter is the total length of the boundary of a geometric shape. For example, the perimeter of a circle is the distance around the circle, which is determined by adding the lengths of all its radii.
Area:
The area is the amount of space inside a geometric shape. For example, the area of a rectangle is determined by multiplying its length and width, and the area of a circle is determined by calculating the square root of its radius.
Symmetry:
A shape is symmetric if it can be divided into two identical halves along a line. For example, a rectangle is symmetric because it can be divided into two identical rectangles with equal area.
Angles:
Angles are measures of the angles formed by two rays that intersect. The sum of the angles in a triangle is always 180 degrees. For example, the sum of the angles in a right triangle is 90 degrees.
Midpoints:
The midpoint is the point that divides a geometric shape into two equal parts. For example, the midpoint of a line segment is the point that divides the line segment into two equal parts.
Lines of Symmetry:
Lines of symmetry are lines that pass through the center of a geometric shape. For example, the lines of symmetry of a circle are the lines that pass through the center of the circle.
Congruence:
Congruence is when two shapes have the same shape and size. For example, a rectangle is congruent to another rectangle with the same dimensions.
Similar Triangles:
Similar triangles are triangles that are similar in shape, but not in size. For example, two triangles are similar if they have the same angles, but they may not have the same side lengths
