E is the midpoint of ab and db is a diagonal of parallelogram abcd what is the ratio of areas of triangle Δabd to parallelogram abcd?

Either diagonal of a parallelogram divides the parallelogram into two triangles of equal areas. Thus area of triangle abd = half that of the parallelogram abcd. The required ratio is 1 / 2.

What are the similarities between an equilateral triangle and a right triangle?
- Like all triangles, the angles must total to 180 degrees. - Both have the same formula for their areas, although the height of an equilateral triangle must be calculated from the side length. - Both have at least 2 acute angles (all three are 60 degrees in an equilateral triangle) and no obtuse angles. - Both figures have three sides. - Both figures have three angles.
How can you say that if areas of two triangles are equal then they are congruent?
In order for a triangle to be congruent the two triangles have to be the same shape and size, thus they are congruent if they can be moved into an isometry or any other combination. But you're asking how a question which has two possibilities. Assuming that you have two triangles whose sides are equivalent which makes the areas equal to each other then you can state the side-side-side rule which is if the three sides of one triangle is equivalent to the other three sides of the other triangle then they are congruent. But if you have an angle present in the triangles you could argue the angle angle side rule, but if the angles are joint you would argue the angle side angle. But if one triangle has one degree and the other one has a different degree then they will not be congruent.

What is the area if the base is 127cm and the height is 10.5cm?
It depends on the shape. A triangle and a parallelogram with these dimensions will have different areas.
How is the area of a triangle different from the area of a parallelogram?
the difference is you bxh for parallelogramand you (bxh)x2 fortrianglea triangle has 4 sides and a parallelogram has 3 obviously they have different areas silly goose. I would know i go to harvard math

What is a diagonal in volleyball?
A diagonal is when the hitter hits the ball in a diagonal direction. Hitters almost always do this because the corners are one of the toughest areas to cover.
How do the areas of the circle and the parallelogram compare?
They both are areas. Just Kidding. Both of them have to have a height and length.
Can a parallelogram and a rectangle have the same perimeters but different areas?
Yes.
Why is the area of a rectangle greater than that of a parallelogram?
Not necessarily. In fact, if a rectangle and parallelogram have the same base and height, their areas are equal.
How is the formula for the area of a trapezoid related to the formula for a area of a parallelogram?
The formula for the area of a trapezoid is a combination of the formulas for the areas of a triangle and a rectangle. It can be seen as two congruent triangles placed together to form a parallelogram. So, the formula for the area of a parallelogram is a generalization of the formula for the area of a trapezoid.
Why is Pythagorean theorem important in geometry?
It finds the third side of the right triangle when the two sides are available. That helps to figure out the circumference of the triangle, it also helps find the length of the diagonal of the square or a rectangle. It helps finding areas and circumpherences of polygons, it helps with construction of polygons, etc... Generally it is one of the most basic and fundamental theorems.
Formula for getting the areas of parallelogram?
base*perpendicular height = area in square units
