How many right triangles can be formed by drawing all three lines of symmetry in an equilateral triangle?
Six
How do you draw a bisector of a triangle?
Find the midpoint of a side and join it to the vertex opposite. That is a median and it divides the mass of a triangle in two halves. Each triangle has three medians. However, there is no reason for a bisector to go through a vertex - it can be a straight line through any point in the triangle. In such a case drawing the bisector analytically is likely to be beyond the skills of most geometry students. There is, though, a very simple practical solution. Cut out a copy of the triangle on a uniform lamina. Suspend it vertically by a pin through the required point. Then the vertical line through that point (use a plumb line) is the bisector of the triangle through that point.
How do you form two triangles by drawing 4 lines?
Make an equilateral triangle(all same sides) with 3 lines and put the 4th on right through the middle and you have 2 right angle triangles.
How many triangles are in a drawing of a pentagram inside a pentagon?
35. To check this, you need to check every possible type of triangle, and then consider that there are 5 of this type (or in one case, 10), and add everything up.
How do you draw a 270 degree angle?
Draw a 'L' shape, but instead of drawing a square for the right angle, draw 3/4 of a circle around the rest of the angle. 360 - 90 = 270. b) don't think so. in a triangle all of the angles have to be line segments. line segments aren't circular. You simply can't draw a 270 degree triangle. its impossible.
