How many different triangles can you draw with area of 20 cm?
Lots! As long as half the length of the base times the height is 20...
Can you explain why the area of a triangle is 1 half base height while the area rectangle or a parallelogram is expressed as base height?
If you draw a diagonal in a rectangle you get two equal triangles, each half the area of the rectangle. Area of rectangle is base x height, so half of that is ½ x base x height. QED
Can two triangles that are not conguent have the same base and height?
Yes. Draw a triangle, then draw line through the top vertex that's parallel to the base. Now draw another point anywhere on that line, and draw sides that meet the edges of the base and the new point you've drawn. No matter where that point is on your line, you haven't changed the height, and you haven't changed the base, but the angles of the triangle have changed. Therefore, the two aren't congruent.
How do you find the area of the triangles if you only have the base and the height?
area =1/2 base length x height
The area of a triangle is found by multiplying the length of its base by its height?
No, a triangles area is calculated from base x height / 2

Why is that if 2 triangles have the same base they have the same area?
Only if the two triangles have the same base and height then they have the same area, because an area of a triangle OS the base times the height divided by two.
How do you draw square pyramid?
You draw a square for the base of the pyramid and then you draw triangles for the 4 faces. Hope this helps!
The area of a triangle is found by multiplying the length of its base by its height?
No, a triangles area is calculated from base x height / 2
Is it true or false that two triangles that have the same base have the same area?
False. The equation for area of a triangle is 1/2 base x height. The height and the base would have to be the same for two triangles to have the same area.
When calculating area what are the similarities between triangles and parallelogram?
Parallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*HeightParallelogram = Base*Height Triangle = 0.5*Base*Height
Are two triangles congruent if they have same area?
Not necessarily. You find the area of a triangle with the formula 1/2*base*height=Area. Imagine two triangles, one with 3 inches for both the base and height, and one with 4.5 inches for the height and 2 inches for the base. Both of these triangles will have 9 sq. in. for their areas, but they are not congruent.
What is the formula for the area of triangles?
A=1/2 base x height
How do you do area of triangles?
area = 1/2 base x height
