... refers to a straight angle as `equal to two right angles’. I don’t know other than historical interest in this. Theorem. If all straight angles are equal then vertical angles are equal This is easy to check that using `common notions’: A +B =A +D implies B =D –in this case for congruence (equality i ...

... Theory: Triangles are similar if they have the same shape, but not necessarily the same size. We will use the right angle created by the rocket during flight to determine its vertical height (h1) as shown in triangle ABC below. Two readings: angle A and the base (b1) will be taken outside. These two ...
