LA; ΔBDA ≅ ΔBDC

Step-by-step explanation:

Segment BD is a leg of the right triangles. It is congruent to itself (whether or not it is marked). Angles A and C are <em>corresponding</em> acute angles in the right triangles. They are marked as congruent to each other.

The triangles are congruent by the LA theorem, applicable to right triangles. The congruency statement can be written as ...

ΔBDA ≅ ΔBDC

The four points (−2, 5), (−2, −1), (6, −1), and (3, 5) are the vertices of a polygon. What is the area, in square units, of this

crimeas [40]

Look at the picture.

The polygon is a right-angled trapezoid.

The area is:
$A=\frac{a+b}{2} \times h$

The points (-2,-1) and (6,-1) lie on the same horizontal line, so the distance between them is 6-(-2)=6+2=8. The length of a is 8 units.
The points (-2,5) and (3,5) lie on the same horizontal line, so the distance between them is 3-(-2)=3+2=5. The length of b is 5 units.
The points (-2,5) and (-2,-1) lie on the same vertical line, so the distance between them is 5-(-1)=5+1=6. The length of h is 6 units.

$A=\frac{8+5}{2} \times 6=\frac{13}{2} \times 6=13 \times 3=39$

The area is 39 square units.
