Equilateral
All three sides are equal in length
Isosceles
Exactly two sides are equal in length
Scalene
All three sides are diffrent lengths
Distance formula
(In log book) √(x2 - x1)2 + (y1 - y1)2

Reflectional symmetry / axial
A shape has reflectional symmetry if it can be divided by a line (a “line of symmetry”) into two parts that are mirror images of each other. E, a heart or butterfly wings
Translational symmetry
The object is not rotated or reflected, it simply moves to a new position.
. Eg A repeating wallpaper pattern or a series of identical tiles on a floor.
Central symmetry
Each point on the shape has a corresponding point directly opposite it, through the center.
Rotation
The shape’s orientation changes, but it remains the same size and shape. Eg : A windmill turning or a clock hand moving
Side-Side-Side (SSS)
Two triangles are congruent if all three pairs of corresponding sides are equal in length
Side-Angle-Side (SAS)
Two triangles are congruent if two pairs of corresponding sides are equal and the angle included between those two sides are also equal
Angle-Side-Angle (ASA)
Two triangles are congruent if two pairs of corresponding angles are equal, and the side included between those two angles is also equal.
Right Angle-Hypotenuse-Side (RHS)
This is a special case for right triangles. Two right triangles are congruent if they have the same length for their hypotenuse, the side opposite the right angle, and for one of their other sides (legs)
