Maths keeps one mentally active.
- Draw x-axis and y-axis, through the origin O.
- In the second quadrant draw a line AB with A at (-6,0) and with a slope of 45 deg. B being on the y-axis.
- Draw another line CD with C at (-4,0) and with a slope of 60 deg.
- Let AB and CD intersect at E.
- You have 4 triangles AOB, ACE, COD, BED.
What shape does 4 triangles make?
There are two layouts of four equilateral triangles that will fold to make a tetrahedron and one that will not. Get students to identify why (two of the triangles fold to be on top of each other, so there is an open side).
What is the maximum amount of triangle that you can make from 4 straight lines?
If you draw 4 straight lines out of each peg you make 4 triangles. In the end, you end up with 32 triangles out of each peg.
How do you draw a triangle with lines?
Draw another quarter-arc that crosses the first arc at a point directly above the line segment. This point is the apex of your triangle. Complete the triangle. Draw the remaining sides of the triangle: two more straight lines will connect the apex with the two open ends of the line segment.
What shape has four squares and triangles?
Square-based pyramid
Square-based pyramid. A pyramid is a shape that has a base and triangular sides. The triangular sides are all the same shape and size. This pyramid has a square base and four triangular sides.
What 4 shapes can you make with 2 triangles?
Rhombus. A rhombus has four equal sides and also has its opposite sides parallel. It is formed by joining two identical isosceles triangles base to base. Its diagonals are not equal but cut each other in half at right angles.
How many angles does 4 triangles have?
A triangle has three angles. The ‘tri-‘ prefix in triangle means three. Because a triangle is a polygon, it has the same number of angles as it has…

Can you make 4 triangles out of 3 triangles?
Move three lines from these three triangles to make four equal triangles. Can you solve this brainteaser without cheating? You’ll be surprised at how easy the answer to this puzzle is.
How do you make 4 half square triangles?
To figure out your own dimensions for making 4 half square triangles at a time you will need to know either the beginning square size you will be cutting or the size of the unfinished block you need. Using the unfinished size half square triangle block you would like, for instance, 4 inches, you will take 4 and divide it by .64.
How to calculate the sides of a triangle?
Enter any valid input (3 side lengths, 2 sides and an angle or 2 angle and a 1 side) and our calculator will do the rest.
How big is a half square triangle block?
Using the unfinished size half square triangle block you would like, for instance, 4 inches, you will take 4 and divide it by.64. That will be the starting size square you will need to cut.
