Theorem 37: If two angles of a triangle are unequal, then the measures of the sides opposite these angles are also unequal, and the longer side is opposite the greater angle. 2. 2. Most computer languages have some way of indicating and working with what is true and what is false, but not all languages choose exactly the same way. Rule 1: Logical or Boolean expressions evaluate to 0 if false, 1 if true. If two opposite sides are parallel, but the other two sides are not, then it is a trapezoidal figure, or simply, 'Trapezoid'. ... the hypotenuse is 2x the side opposite the vertices, the angle adjacent to that side is a right angle. Vertically Opposite Angles. Answer: a = 140°, b = 40° and c = 140°. We can think of these as opposite angles formed by an X. (b) Two obtuse angles can form a linear pair (c) Two right angles can form a linear pair (d) One obtuse angle and one acute angle cannot form a … 108 The interior angles of a triangle are in the ratio 1:2:3, then the ratio of its exterior angles is 3 : 2 : 1.
