What is the formula for a triangular pyramid in surface area?
A=1/2bh The area of a triangle is 1/2bh. If the base of it is a triangle and all 4 of the triangles aren't the same, then you have to find the area of the base triangle and then the three other triangles (which should all have the same area). If all four of the triangles have the same area, then just find the area of one of the triangles and multiply that by four. A triangular pyramid that has four equal triangles is also called a tetrahedron.
How can you find the area of a polygon that is not one for which you know an area formula?
Divide the polygon into triangles. Calculate the areas of the triangles and then sum these.
How do you find aras of triangles and parallelograms?
Triangles you use : (base x perpendicular height) divided by 2. Parallelogram: you need to find the area of one of the side triangles, then double it (because there's two of them). Then find the area of the square in the middle, and add this to the area of the two triangles.
Triangles are congruent if the have the same?
area
When you are finding the area of a triangle do you do the same for all types of triangles?
yes. When you are finding the area of a triangle you do the same for all types of triangles.
Do all triangles with same side lengths have the same area?
Only if they are congruent triangles
Do congruent triangles have the same area?
yes
If two triangles are congruent do they have the same area?
yes they have same area
Does the formula for the area of a triangle pertain to all triangles including scalene triangles?
The title of the formula is "Formula for the Area of a Triangle". No discrimination is expressed or implied.
How many different triangles can you draw with an area of 24 square units?
There are an infinite number of triangles with different shapes that all have the same area.
What condition for a triangle produce triangles that have the same area?
If another triangle has the same three sides, that is, sides of the same length, it will have the same area. Note that this is a sufficient, but not a necessary, condition, since you can also have triangles of a different shape that have the same area.
How do you find the area of triangles?
area = 1/2 base x height
