QUESTIONS AND CORRECT ANSWERS
Which set of equations is enough information to prove that lines c and d are parallel lines cut
by transversal p? - CORRECT ANSWERS✅✅m∠2 = 99° and m∠4 = 99°
Which statements about the diagram are true? Select three options. - CORRECT
ANSWERS✅✅x = 63
z = 117
x + z = 180
If = 3.2 ft, which is a possible measure of ? - CORRECT ANSWERS✅✅3.2 ft
Which figures are shown in the diagram? Select three options. - CORRECT
ANSWERS✅✅point D
ray CD
ray DC
We are given that AB = 12 and AC = 6. Applying the segment addition property, we get AC
+ CB = AB. Applying the substitution property, we get 6 + CB = 12. The subtraction
property can be used to find CB = 6. The symmetric property shows that 6 = AC. Since CB =
6 and 6 = AC, AC = CB by the property. So, AC ≅ CB by the definition of congruent
segments. Finally, C is the midpoint of AB because it divides AB into two congruent
segments. - CORRECT ANSWERS✅✅b
It is given that M is the midpoint of and . Midpoints divide a segment into two congruent
segments, so . Since and perpendicular lines intersect at right angles, and are right angles.
Right angles are congruent, so . The triangles share , and the reflexive property justifies that .
Therefore, by the SAS congruence theorem. Thus, because _____________. Finally, ΔPKB
is isosceles because it has two congruent sides. - CORRECT ANSWERS✅✅corresponding
parts of congruent triangles are congruent
If m1=61.8°, then what is the measure of m6? - CORRECT ANSWERS✅✅118.2°
