David W. Sabo (2003) Triangles Page 2 of 5; A; B; 380; Properties of Triangles; For every plane triangle, the vertex angles always add up to 1800: A+B+C=1800; Example: Two angles in a triangle are 63.60 and 42.10. Determine the third angle. ... Such a line is called an altitude of the triangle. Obviously,

The two equal sides are 10cm and the base is 12cm. ... You can find the height by cutting the triangle in half so that one of the 2 equal sides is the hypotenuse then use Pythagorean's formula: a² + b² = c²; (12/2)² + h² = 10² h² = 100 - 6² h² = 64 h = 8cm;
