Area of a Triangle

Please answers the following questions in the space provided below

1. Identify the height and base of rectangle [b][i]AEFB[/i][/b]?[br][br]2. [i][u]How[/u][/i] do you calculate the area of a rectangle?[br][br]3. Calculate is the area of a rectangle [b][i]AEFB.[/i][/b][br]

Point C should be on the segment between points E and F, to form ∆ACB. ∆ACB is known as an acute triangle.

Please type your answers in the space below.[br][br]1. What is the definition of an acute triangle?[br][br]2. Is the [i][u]height[/u][/i] of acute ∆ACB located Inside the triangle or outside the triangle?[br][br]3. Calculate the area of[b][i] ∆[/i][/b][b][i]ACB[/i][/b]? [br][br]4. What conclusion can you make about the area of rectangle [b][i]AEFB[/i][/b] and [b][i]∆[/i][/b][b][i]ACB[/i][/b]?[br]

Place point C right on top of point F to make ∆ACB a right triangle.

Please type your answers in space below.[br][br]1. What is the definition of a right triangle?[br][br]2. Is the height of right ∆ACB located inside the triangle or outside the triangle?[br][br]3. Calculate the area of [b][i]∆[/i][/b][b][i]ACB[/i][/b]?[br][br]4. What conclusion can you make about the area of rectangle [b][i]AEFB[/i][/b] and [b][i]∆[/i][/b][b][i]ACB[/i][/b]?[br]

Place point C two spaces to the left of point F (point C is no longer be on segment EF), to make ∆ACB an obtuse triangle.
