Projection of a side of a triangle

1. TOPIC:
PROJECTION OF A SIDE OF
A TRIANGLE

2. • TRIANGLE:
A triangle is a polygon with three
edges and three vertices. It is one of the basic shapes in
geometry. A triangle with vertices A, B, and C is
denoted △ A B C.
A
B C

3. TYPES OF TRIANGLES

4. • Acute triangles:
Acute triangles are triangles
in which the measures of all three angles are
less than 90 degrees.

5. • Obtuse triangles:
Obtuse triangles are
triangles in which the measure of one angle is
greater than 90 degrees.

6. • Equilateral triangles:
Equilateral triangles are
triangles in which all three sides are the same
length.

7. • Right triangles:
Right triangles are
triangles in which the measure of one angle
equals 90 degrees.

8. • Isosceles triangles:
Isosceles triangles are triangles
in which two of the sides have the same length.

9. • Scalene triangles:
scalene triangles are
triangles in which none of the sides are the
same length.
