I think the correct answer from the choices listed above is option C. If triangle abc= def by side-side-side triangle congruence theorem, then b=e by Corresponding parts of congruence. CPCTC states that if two or more triangles arecongruent<span>, then all of their </span>corresponding<span> angles and </span>sides<span> are </span>congruent<span> as well.</span>

Answer: D: Corresponding parts of congruent triangles are congruent


Step-by-step explanation:

If two triangle are congruent using postulate of theorems of congruence then their corresponding parts are congruent by CPCTC rule.

The CPCTC rule says that if two triangles are congruent then their each corresponding part whether angles or sides must be equal.

Here if triangle abc= def by side-side-side triangle congruence theorem,

then b=e [which is a corresponding part of both triangles] by Corresponding parts of congruent triangles are congruent.

10. Polygon WXYZ has vertices W(-1.5, 1.5),
vovikov84 [41]

Answer:

See explanation

Step-by-step explanation:

Polygon WXYZ has vertices W(-1.5, 1.5), X(6, 1.5), Y(6, -4.5), and Z(-1.5, -4.5).

Find the slopes of all sides:

WX:\ \dfrac{1.5-1.5}{6-(-1.5)}=\dfrac{0}{7.5}=0 - horizontal line

XY:\ \dfrac{-4.5-1.5}{6-6}=\dfrac{-6}{0} - slope undefined, so the line is vertical

YZ:\ \dfrac{-4.5-(-4.5)}{-1.5-6}=\dfrac{0}{-7.5}=0 - horizontal line

ZW:\ \dfrac{1.5-(-4.5)}{-1.5-(-1.5)}=\dfrac{6}{0} - slope undefined, so the line is vertical

Vertical and horizontal lines are perpendicular, so all angles W, X, Y and Z are right angles. Hence, quadrilateral WXYZ is a rectangle

SAS similarity. the angle degree is the same. if you multiply 14 and 8 by a factor of 7 you get 98 and 56 which means the triangle have the same ratio making them similar. because of this ratio it makes the side similar therefore being a SAS similarity because the angle is between the sides.
