Sketching
triangles with two specific
two specific angle measurements Objective: 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 measurement.
2.- First, place the center of the protractor at point A and measure 55 degrees. Second, place the center of the protractor at point B and measure 35 degrees.

3.- Increase the length of the
sides of
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. ( see figure ) |
