You don't have to do anything at all. As soon as you draw a triangle, it automatically
has area. The only trick for you is to figure out how much area it has.
Draw a right angled triangle with legs of 4cm and 6cm
Yes
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.
The area of qa triangle is always half of the area of a rectangle with the same dimensions
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.
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.

Most people, when asked to draw a triangle, would probably draw an acute or maybe a right triangle.
There are many different triangles that have an area of three square inches, here's one way to draw one: Draw a rectangle whose area is six square inches (or imagine what one's dimensions would be, e.g. 6x1 or 3x2) and cut it in half diagonally to make a right triangle that has an area of three square inches.
-- Just go ahead and draw a triangle. Any triangle.-- Did you do it ? Good.-- Your triangle has three angles in it.
first draw a triangle, then a rectangle, and lastly draw another triangle on both side of the rectangle... if you want draw a smoke at the bottom.
You can draw a triangle with two obtuse angles in a sphere
