Properties of TrianglesVersion en ligne This quiz is based on the fundamental properties of triangles. Test your knowledge about angle sums, types of triangles, and key formulas. Reference: Asif, M. (2019). Properties of triangles – Important formulas and classification. par José Gonzalez Romero 1 What is the sum of the interior angles of any triangle? a 90° b 180° c 270° d 360° 2 In a right triangle, the two non-right angles always: a Sum to 180° b Sum to 90° c Are equal d Sum to 45° 3 What is the name of the longest side in a right triangle? a Leg b Base c Hypotenuse d Height 4 In an equilateral triangle, all interior angles measure: a 45° b 30° c 90° d 60° 5 The formula for the area of a triangle is: a base × height b ½ × base × height c base + height d 2 × base × height Feedback 1 The angle sum property states that the interior angles of any triangle always add up to 180°, regardless of its type. 2 Since one angle is already 90°, the remaining two angles must sum to 90° to complete the 180° total. 3 The hypotenuse is always the side opposite the right angle and is the longest side of a right triangle. 4 In an equilateral triangle all three sides and all three angles are equal, so each angle measures 180° ÷ 3 = 60°. 5 The standard area formula for any triangle is ½ × base × height, where the height must be perpendicular to the base.
