how to draw similar triangles?

Answer 1

I noticed you said *similar* triangles, not congruent.

To do that, you could just extend out two of the sides using a straight edge, then add an additional parallel line to the 3rd side. That would create 2 similar triangles.

For example, if your first triangle was ABC, you could extend side AB to a point D, where AD was twice as long as AB. (Set your compass to the length of AB, then mark BD the same distance along the extended line.)

Similarly you could extend AC out to a point E where AE was twice as long as AC. Connecting line DE, you would have a similar triangle ADE.

Answer 2

The easiest is with the use of a compass. Draw a line with length proportional to the length of one side of the triangle to be copied. At both ends, draw an arcs with a radii that are proportional to the other two sides. The intersection gives you the third corner.

Answer 3

Just drop a perpendicular from any of the its vertex of a triangle on to is corresponding side(opposite side).This line is called height of the triangle. Now produce base on either side and the height. Then, go on joining subsequent and corresponding points on the produced lines. You will get infinite number of similar triangles.

Answer 4

Drawing similar triangles isnt big deal.
Just take ur protractor and draw two triangles of similar angles (all the 3 angles).

Answer 5

draw a triangle and measure all the sides accurately then draw similar triangles using the same measurements.
