Tri Angles - Picturing a Triangle Assignment

On a recent trip to Recife, Brazil, we saw a lot of old churches still standing since the early colonization of Brazil by the Portuguese. This picture of the church, shows both an obtuse (left) and acute (right) isosceles triangle. These triangles form the roofs of the church. The roof on the left is an obtuse isosceles because the two sloping sides are congruent and the vertex that is created by those sides is obtuse (greater than 90 degrees). The right roof is an acute isosceles because the two congruent sides form an acute angle (less than 90 degrees).

Close to my house, I walk by The Louvre everyday going to cooking class. The four faces of the pyramid at The Louvre are made up of equilateral triangles. The sides are all congruent as well as all the vertices of the triangle. This is also known as a regular triangle because of it's unique properties. In addition to the large pyramid, there are also three others that have pyramidal faces that are equilateral triangles.
