A triangle is a three-sided polygon, existing in various lengths and forms. To calculate square footage of a triangular shape, you need to calculate the area of the triangle with feet as the unit of measurement.Know More
Measure the length of the base and the height of the triangle. The base can be any side, but make sure it is consistent throughout the entire process. The height of the triangle is simply the distance from the opposite corner to the base. When measuring height, your measurement should be at a 90-degree angle from the base. Also ensure that you are measuring in feet. This guarantees that your area ends up being measured in square footage.
The equation for calculating the area of a triangle is ½ multiplied by the base multiplied by the height. Take the base and height measurements in Step 1 and multiply them together, and then divide the product of these measurements by 2.
Do the math and solve the equation. If you perform this calculation correctly, you should have the square footage of your triangle. To check your work, divide your answer by two variables. If your answer was correct, this number should be your third variable.
A triangular prism has six vertices. In order to calculate the number of vertices on any type of prism, take the number of corners on one side and multiply by two. For example, a rectangular prism has eight vertices, or two sets of four.Full Answer >
Calculate the square footage of the room by measuring the length and width, rounding up to the nearest half-foot, and then multiplying these numbers to get the number of square feet. Rooms with non-rectangular shapes require additional calculations.Full Answer >
A triangle has either two or three acute angles, depending on the type of triangle. Right and obtuse triangles have two acute angles, whereas an acute triangle has three acute angles.Full Answer >
