Proofs of a triangle

WebThe fallacy of the isosceles triangle, from (Maxwell 1959, Chapter II, § 1), purports to show that every triangle is isosceles, meaning that two sides of the triangle are congruent. This fallacy was known to Lewis Carroll and may have been discovered by him. It was published in 1899. Given a triangle ABC, prove that AB = AC: WebSum of the measures of two angles = 75° + 60° = 135°. Using the properties of a triangle, we know that the sum of all three angles of triangle = 180°. Therefore, the measure of the third angle = 180° - 135° = 45°. Example 2: Tim wants to construct a triangle with the lengths of sides 5 cm, 4 cm, and 9 cm.
