Do you know the formula for the area of a triangle ?

Pick a base-length and a height for your triangle so that 1/2 (base x height) = 20.

Do you know the formula for the area of a parallelogram ?

Pick a base-length and a height for your parallelogram so that (base x height) = 20.

We're having a problem understanding your difficulty.

Of course, if you don't know the formulas for area . . .

draw a parallelogram which is not a rectangle.verify that its area is equal to the rectangle on the same base and altitude

== == 1) Draw a line segment AB of 5 units 2) Draw the perpendicular bisector CD of AB such that Cd meerts AB at C. 3) Mark off CE = 2 units on CD 4) Draw the straight line segments AE & BE. ABE is your triangle. Its base (AB) = 5 and height (CE) = 2, so its area = [base x ht] / 2 = 5 sq units

You don't have to do anything at all. As soon as you draw a triangle, it automaticallyhas area. The only trick for you is to figure out how much area it has.

Draw a straight line AB of any length x. Draw another line, parallel to AB and at a distance of 2*24/x units from it. Select any point on the second line and call that point C. Join AC and BC. Then triangle ABC will have an area of 24 square units.

Draw a right angled triangle with legs of 4cm and 6cm

Easiest wayDraw a three inch by three inch square. add lines at one inch marks to form a small grid. draw line diagonally across to form two triangles. count the number of squares in one triangle (remember the squares with the diagonal line are only half a square)Did you get 4 1/2?A X B divided by two 3 X 3= 9 / 2 = 4.5To arrive to the forumla for area of triangle, lets look at the area of square and rectanlge first: Area of square: side x side Area of rectangle: length x width Notice that the formulas for area of square and rectangle is very similar. The squre is a special case only, so there is not much difference. Let's take the special case first- area of square: Area= side x side If I want to find the area of a triangle from this square, you have to divide the square in half diagonally. This means: (side x side)/2 = area of triangle Let's take a look at retangle now: Area of rectangle: length x width Similarly like the square, you divide the rectangle diagonally by half. This means: (length x width)/2 Conclusion: Thus, area of triangle= (base x height)/2 The base can be considered as one of the sides of the rectangle/square, and the height can be considered as the other side of the rectangle/square. THE FORMULA OF TRIANGLE COMES FROM HALF THE AREA OF RECTANGLE/SQUARE! Visit for more math help and tutoring!Area is measured in square units. If we are given a region we divide the region into unit squares.Then we count the number squares, which is the area of the region.Consider a rectangle of length 10 units and width 5 units.The area of the rectangle is 50 square units.It is because we can divide the rectangle into 10 equal parts along the length.Similarly, we can divide the rectangle into 5 equal parts along the width. Now we have divided the entire rectangle into unit squares.If we count the number of squares we get 50 unit squares.We get this by multiplying the length and the width. Area = Length*Width square units.This is the same for a parallelogram too.Area of a parallelogram is base * height square unitsThis is how the concept of area has come.We can find the area of the triangle also.A rectangle or a parallelogram can be divided into two equal triangles by a diagonal.Half of the area of the rectangle(or parallelogram) gives the area of the triangle.In fact, we can extend any triangle into an parallelogram.So, we get the formula, area of a triangle = (base* height)/2 square units.Source:

First draw a rectangle with an area of 6 square units - for example 2 units x 3 units. Then "slide" the topmost side along its length through any distance of your choice. (You could slide any side along its own length.) The length of the base has not been altered and, since the top was slid along its length, the vertical height has not been changed either. So the area remains unchanged at 6 sq units.

A right-angle triangle is half of a square or rectangle. Draw a square or rectangle and draw a line from one corner to the corner diagonally opposite. You now have two triangles of the same area.

Draw a right angled triangle with legs of lengths 2 and 3 units. The hypotenuse will be sqrt(13) units.

Right triange with both sides around the 90 degrees = 4 with a right trianle the area = 1/2 * height * width (think of it as half a rectangle)

YES From your start point draw a line 5 units up, from this point draw a line 5 units across, from this point draw a line 5 units down, from this point draw a line 5 units back to the start. You have drawn a square with a total perimeter length of 20 units and a area of 25 square units.

Because - if you draw lines at right-angles from the base of a triangle vertically until they reach the highest point, then draw a horizontal line that connects those points, touching the highest point of the triangle - the area outside the triangle (but inside the resulting quadrilateral) is exactly half the area of the quadrilateral.

The area of qa triangle is always half of the area of a rectangle with the same dimensions

Well, it helps immensely to know the formula for the area of a triangle. The area of a triangle is 1/2 (length of the base) times (height) .Knowing that, all you have to do is draw a triangle in such a way that the length of the base (in cm), multiplied by the height (in cm) is 12 . There are an infinite number of ways to do it, so finding one should not be a problem.

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

Most people, when asked to draw a triangle, would probably draw an acute or maybe a right triangle.

Draw a line of best fit through the plotted points which will give the y intercept. Draw a right angle triangle under the line which will be the triangles hypotenuse. Divide the vertical units of the triangle by the horizontal units which will give the value of the slope.

first you draw a equal triangle then you draw an upside triangle in the same place

please give me the picture I will give you a big jucy kiss if you do.

No. Every square is a rectangle, a rhombus, a parallelogram, and a regular quadrilateral.
