The angle bisector, median, and altitude are all the same things in an isosceles triangle.
That means that the legs of the smaller triangles created by the altitude are 4 root 2.
By special properties of an right triangle, the hypotenuse is 8.
Since the legs of the original right triangle are congruent, the area of the original triangle is 8*8/2.
Now we just simplify:
8*8/2=64/2=32
The answer is B, because if you draw the baseboards on the scale drawing, you'll get nineteen baseboards. 19 x 4,19 = 79,61
Answer:F B G E A
Step-by-step explanation:
1. F( a rigid transformation only changes the position but the size and angles remain the same)
2. B(The angle of rotation symmetry is the smallest angle the figure can be rotated to coincide with itself.)
3. G(Congruent means that it is the same size and shape)
4. E(Translation moves the whole shape including the points so that the shape and sizes remain the same)
5. A(Though it's position may change, reflective symmetry ensures that no other parts of the shape can change no matter what.)

Answer:
Total
Step-by-step explanation:
