If you are drawing an acute angle (less than 90 degrees… A triangle if its perimeter is 10.4 cm and two angles are 45° and 120°. The kids must draw the given angles using a protractor. Construct a triangle whose sides are 3.6 cm , 3.0 cm and 4. We look at how much the angle has “opened” as compared to the full circle. This will become the vertex (corner) of the angle. Explore this array of drawing angles worksheets and comprehend the construction of acute, obtuse, and reflex angles. Construct a △ABC with base BC = 3.5 cm, vertical angle ∠BAC = 45˚ and median through the vertex A is 3.5 cm . Why don't libraries smell like bookstores? Join the vertex B to the small dot with a ruler to form the second arm, BC, of the angle. This is obtuse, 110 degrees. Align your reference line with the protractor's baseline and mark the paper at the degree of measurement. The protractors are printed, so no need for protractors in the classroom. So let me type it in. Thus, ∠ROA = ∠ROQ = 40° + 80°= 120°. Align your reference line with the protractor's baseline and mark the paper at the degree of measurement.
