WebbAngles: 30°: 60°: 90° Ratio of sides: 1:√ 3 :2 Side lengths: a:5:c Then using the known ratios of the sides of this special type of triangle: a = b √ 3 = 5 √ 3 c = b × 2 √ 3 = 10 √ 3 As can be seen from the above, knowing just one side of a 30°-60°-90° triangle enables you to determine the length of any of the other sides relatively easily. WebbAn acute angle is formed when two rays intersect at the vertex and form an angle smaller than 90°. Some examples of acute angles are 20°, 40°, 60°, and 80°. Obtuse Angle Obtuse angles are any angles that measure greater than 90° and smaller than 180°. Some examples of obtuse angles include 110°, 130°, 145°, and 165°. Straight Angle
