Question 68325This question is from textbook Geometry
: Multi-Step Problem. You can use the method described below to approximate the distance across a stream without getting wet. As shown in the diagram you need a - Stand on the edge of the stream and look straight across to a point on the other edge of the stream. Adjust the visor of your cap so that its in the line with that point.
- Without changing the inclination of your neck and head, turn sideways until the visor is in line with a point on your side of the stream.
- Measure the distance BD between your feet and that point.
QUESTIONS
a.) From the description of the measuring method, what corresponding parts of the 2 triangles can you assume are congruent?
b.) What theorem or postulate can be used to show that the 2 triangles are congruent?
c.) Explain why the length of BD is also the distance across the stream. This question is from textbook Geometry

QUESTIONS
a.) From the description of the measuring method, what corresponding parts of the 2 triangles can you assume are congruent?
The angle your body makes with the ground is a rt. angle; The angle made
by your body and the line to the opposite shore and/or the distant object
The side from your feet to the opposite shore and/or the side from your
feet to the distant object. The side formed by your body in both triangles.
b.) What theorem or postulate can be used to show that the 2 triangles are congruent? Side-Angle-Side
c.) Explain why the length of BD is also the distance across the stream.
Corresponding parts of congruent triangles.
