Try Your Hand at Drawing Triangles
1 point
In this activity, you will draw six triangles: an isosceles triangle, an equilateral triangle, a
scalene triangle, a right triangle, and acute triangle, and an obtuse triangle.
*You are to:
1). name each triangle
2). label the measurements of ALL of its sides AND angles
3). color it
When you are done, you will have a poster of triangles.
The following information will help you draw the triangles accurately:
*Isosceles triangles have at least two congruent sides.
*Equilateral triangles have three congruent sides.
*Scalene triangles have no congruent sides.
*Right triangles have one right angle.
*Acute triangles have three acute angles.
*Obtuse triangles have one obtuse angle.
*In every triangle, the sum of the measures of the angles equals 180˚.
Use the following information to construct the triangles. Remember to label the measures
of all sides and angles.
1. Draw an isosceles triangle. One side is 5 inches and one angle is 70˚.
2. Draw an equilateral triangle. One side is 4 inches.
3. Draw a scalene triangle. One angle measures 20˚ and another angle measures 85˚.
4. Draw a right triangle. One side is 4 inches.
5. Draw an acute triangle. One side is 5 inches and another side is 7 inches.
6. Draw an obtuse triangle. One side is 6 inches and another side is 4 inches.
*If doing this project, you are to use a large piece of white construction paper. That is
the only paper this can be done on.
*You may also sign out a protractor to measure your angles, unless you have one at home
to use.
*Neatness counts.
*Suggestion: Practice drawing each triangle on a scrap piece of paper before putting the
final triangle on the poster.
