Decide whether each is a valid method of showing that two quadrilaterals are similar. Justify your answer a. AAA b. AAAA

Solution

a) If we know three angles of a quadrilateral , we can calculate the fourth angle.

so, if three angles of a quadrilateral are similar, then the fourth angle is also similar.

Hence the two quadrilaterals are similar.

b)Similarly if given four angles of a quadrilateral are equal,

It shows that the shape and geometry of the two quadrilatlerals are similar.

Hence we can say that the two triangles are similar.
