Question

1. A trough is formed by nailing together edge to edge, two boards 11 ft. in length, so that the right section is a right triangle. If 15 gal. of water are poured into the trough and if the trough is held level so that a right section of the water is an isosceles triangle, how deep is the water ( 231 cu.in. = 1 gal.)

2. The edges of a trunk are 3 ft, 4 ft and 6 ft. A second trunk is twice as long; the other edges are 3 ft and 4 ft. How do their volumes compare?

Polygon with three sides, three angles, and three vertices. Based on the properties of each side, the types of triangles are scalene (triangle with three three different lengths and three different angles), isosceles (angle with two equal sides and two equal angles), and equilateral (three equal sides and three angles of 60°). The types of angles are acute (less than 90°); obtuse (greater than 90°); and right (90°).
