What has the same relative position in similar figures?

same relative position. Two figures are similar if and only if the lengths of corresponding sides are proportional and all pairs of corresponding angles have equal measures.

What are two angles that are in the same relative position called?

When two or more lines are cut by a transversal, the angles which occupy the same relative position are called corresponding angles . When the lines are parallel, the corresponding angles are congruent .

Are sides that have the same relative positions in geometric figures?

Corresponding Sides: Sides that have the same relative positions in geometric figures • Dilation: Transformation that changes the size of a figure, but not the shape.

What are angles that have the same relative position in geometric figures?

Corresponding angles are angles that have the same relative positions in corresponding geometric figures. 8.

What is the new figure after a transformation called?

image

What is the final figure called?

Terms in this set (17) maps an initial figure, called a preimage, onto a final figure , called an image. a transformation representing a flip of a figure. Figures may be reflected in a point, line or plane.

How do you prove corresponding angles are congruent?

Imagine translating one of the angles along the transversal until it meets the second parallel line. It will match its corresponding angle exactly. This is known as the corresponding angle postulate: If two parallel lines are cut by a transversal, then the corresponding angles are congruent.

Can corresponding angles not be congruent?

Not all corresponding angles are equal. Corresponding angles are equal if the transversal intersects two parallel lines. If the transversal intersects non-parallel lines, the corresponding angles formed are not congruent and are not related in any way.
