triangle having only 2 sides of equal length
scalene triangle
triangle having 3 sides with 3 different lengths
equivalent fractions
fractions that have the same value but are expressed with different numbers. 4/8 and 2/4
congruent figures
figures with indenical angles and sides of equal length. they are the same shape and size
perpendicular lines
lines that intersect to form "square corners" or right angles (90 degrees) where they cross

Translation:
The movement of a geometric figure without changing its appearance. SLIDE
Rotation:
To turn a figure around a point TURN
Line of symmetry:
