Question

6. Andre is drawing a triangle that is congruent to this one.He begins by constructing an angle congruent to angleLKJ. What is the least amount of additional informationthat Andre needs to construct a triangle congruent tothis one?

Answer 1

The measure of an angle

The measure of two legs

1) Andre can construct a congruent triangle using SAS congruence, knowing the angle congruent to LKJ and with a compass measure two legs of that triangle

2) Sketching out we have:

Notice that either with a protractor or with a compass we can measure congruent angles and based on SAS congruence we need two congruent legs to determine a SAS congruence.

3) Hence, Andre needs at least:

The measure of an angle

The measure of two legs
