![]() Sides of separate figures that are opposite corresponding angles.Ī six-sided polyhedron that has congruent squares as faces.Ī solid figure with a pair of circular, parallel bases and a round, smooth face between them. Two angles whose measurements add up to 90º.Ī solid figure with a single circular base and a round, smooth face that diminishes to a single point.Īngles of separate figures that are in the same position within each figure. If the trough is being filled with water at the rate of 12000 cm/min, how fast (in cm/min) is the water level rising when the water is 10 cm. The distance around a circle, calculated by the formula \(C = \pi d\). :5 VIEW LIST A water trough is 1000 cm long and a cross-section has the shape of an isosceles trapezoid that is 50 cm wide at the bottom, 80 cm wide at the top and has a height of 30 cm. The amount of space inside a two-dimensional shape, measured in square units. The volume of the prism is 234 cubic units. Each hexagon is made from 2 congruent isosceles trapezoids. The sum of opposite angles is equal to the straight angle (180 degrees). But an isosceles trapezoid has no rotational symmetry (unless it is a rectangle). An isosceles trapezoid has an axis of symmetry - the line of symmetry goes through the midpoints of the bases. ^3\).Ī figure formed by the joining of two rays with a common endpoint. REALLY IMPORTANT A prism has 2 congruent hexagonal bases like the one shown. An isosceles trapezoid which is also a right trapezoid is a rectangle.
