An enlargement changes the sides but keeps the same angles
A rigid motion transformation is one that preserves distances and angles between points in a geometric shape. Anything that involves changing the size or shape of the object, such as scaling or shearing, would not describe a rigid motion transformation.
A conformal map preserves shape, meaning angles are maintained. A equal-area map preserves size, meaning areas are accurately represented.
A protractor measures the degree of angles and circles.
congruent angles
Supplementary angles are 2 angles whose measures = 180o.
Two angles are complementary if the sum of their measures is 90 degrees.Two angles are supplementary if the sum of their measures is 180 degrees.
