Use your protractor, compass and writing utensil to construct the following triangles according to the classifications given:

1.) Obtuse Isosceles triangle. (Angle = 120° and legs 2 inches long.)
2.) Right Scalene triangle:
3.) Equilateral triangle: (Sides of length 2 inches.

Answer 1

The diagrams of the triangles are attached below.

The steps to draw the triangle are as follows:

Choose a starting point: Mark a point on your paper. This will be one vertex of the triangle.

Set the compass distance: Using your compass, set the distance between the point and the center of the compass to 2 inches. This will be the length of each side of the triangle.

Draw the first arc: Place the compass point on the chosen starting point and draw an arc.

Move the compass point: Without changing the compass setting, move the compass point to the intersection of the first arc with the circle you just drew. Draw another arc.

Find the third vertex: The intersection of the second arc with the first arc is the third vertex of the triangle.

Connect the vertices: Draw straight lines connecting the three vertices to complete the equilateral triangle.
