Geometry
Activity II
If so instructed by your teacher, print out a worksheet page for these
problems.
Open the slide called
Glide Angle (with
text) to learn about how a glide angle measures the flying efficiency
of the glider
If a glider is in
a steady (constant velocity and no acceleration) descent, it loses altitude
as it travels across the ground. The glider's flight path will be a simple
straight line, shown as the inclined red line in the figure. The flight
path will intersect the ground at an angle "a" called the glide angle.
The top line in the figure represents the horizontal path of the plane
before its descent and is parallel to the ground.
Problem:
Prove angle a is congruent
to angle b, given the above relationships.
