1. The pair of vertical angles from the attached diagram are:<B and <D (OPTION B)<A and <C (OPTION C)Vertical angles (which are also known as opposite angles) are a pair of non-adjacent angles which are formed by the intersection of two lines. A pair of vertical angles have an equal measure. 2. FalseA rigid transformation DOES NOT result in a figure that is twice as large as the original. A rigid transformation preserves length, therefore it results in a figure that is just as large as the original. Rigid transformation is also called an isometry. 3. The following options (B, D, E, F and H) are the congruent triangles facts that are sufficient to prove triangles congruent
b. SAS (side-angle-side)
d. SSS (side-side-side)
e. HL (hypotenuse leg)
f. AAS (angle-angle-side)
h. ASA (angle-side-angle) 4. Perpendicular lines is the term used in elementary geometry to describe two lines that intersect and form right angles (90 degrees). Perpendicularity is a symmetric property, that is, if line A is perpendicular to line B, then line B is also perpendicular to line A.
