triangles with two specific
two specific angle measurements
Sketch a triangle with the following degree measurements:
Angle A = 55 degrees
Angle B = 35 degrees
1.- Draw a line segment ( AB ).
- Segment AB can be of any
2.- First, place the center of the
protractor at point A and measure
Second, place the center of the
protractor at point B and measure
|3.- Increase the length of the
the angles until they intersect
( point C ).
- The dotted lines indicate that if you
draw the sides to long they have
to be erased to form a perfect triangle.
| 4.- Knowing angle A
and angle B,
find the length of angle C.
