CUMULATIVE EXAM 2025 WITH 100%
ACCURATE SOLUTIONS
Triangle ABC is isosceles.
What is the measure of angle C? - Precise Answer ✔✔75°
Line ST and point V are shown on the graph.
Line VW is to be drawn on the graph such that it is perpendicular to line ST. If the coordinates of point W
are (−1, y), what is the value of y? - Precise Answer ✔✔3
What is the length of SA? - Precise Answer ✔✔3 ft
Planes A and B are shown.
If a new line, p, is drawn parallel to line l, which statement is true? - Precise Answer ✔✔Line p must be
perpendicular to line m.
Which composition of similarity transformations maps LMN to L'M'N'? - Precise Answer ✔✔a dilation
with a scale factor greater than 1 and then a translation
What is the equation of the line that is parallel to the given line and passes through the point (12, −2)? -
Precise Answer ✔✔y =5/6x - 12
Which congruence theorems can be used to prove ΔEFG ≅ ΔJHG? Select two options. - Precise Answer
✔✔ASA
AAS
, Myra took a picture of the sky one afternoon when two jet airplanes appeared to draw a pair of parallel
lines with their vapor trails. The vapor trails from two other jets flying from another direction crossed
over the parallel trails. She printed her picture and labeled the angles and lines.
Assume lines c and d are parallel and 2 measures 98°. Which statements are true? Select three options. -
Precise Answer ✔✔3 = 6 = 98°
4 = 8 = 82°
5 = 8 = 82°
What is the pre-image of vertex A' if the image shown on the graph was created by a reflection across
the line y = x? - Precise Answer ✔✔(10, -2)
Is there a series of rigid transformations that could map ΔRST to ΔXYT? If so, which transformations could
be used? - Precise Answer ✔✔Yes, ΔRST can be translated so that S is mapped to Y and then rotated
about S so that R is mapped to X.
Given: a ∥ b and ∠1 ≅ ∠3
Prove: e ∥ f
We know that angle 1 is congruent to angle 3 and that line a is parallel to line b because they are given.
We see that __________ by the alternate exterior angles theorem. Therefore, angle 2 is congruent to
angle 3 by the transitive property. So, we can conclude that lines e and f are parallel by the converse
alternate exterior angles theorem.
Which information is missing in the paragraph proof? - Precise Answer ✔✔∠1 ≅ ∠2
Triangle NLM is reflected over the line segment as shown, forming triangle ABC. Which congruency
statement is correct? - Precise Answer ✔✔ΔNLM ≅ ΔCAB
Given: AB = 12AC = 6Prove: C is the midpoint of AB.
