Why is a set square called a set square even though it is a triangle?

A set square is known as a set square and not triangle because when you divide 180 by 4, then you get 45. Now, if you construct a square with side: 45 degrees and then divide it in half, then you get the measurement 45-45-90.

Yes, it won't be exact, but you can round the number to get a close estimate.
What kind of triangle has 3 en even sides?
An equilateral triangle.
Is 9 over 64 a perfect square?
Even though 9/64 is 3/8 multiplied by itself, the term "perfect square" only applies to integers.
Closed figures made up of line segments are called?
traingle* * * * *Not quite. A triangle (even) is one example, but the general answer is a polygon.
Why surface area is measured in square units even though the figure is three dimensional?
because you are just measuring the outside faces, therefore it is only measured in square units
What is a triangle with 2 even sides called?
scalene triangle
A triangle having no even sides?
Is called a scalene triangle.
What number is a triangle number a square and an even number?

What is a triangle called with two even sides?
Isosceles
How are a square and triangle different?
A square has four sides whereas a triangle has only three. A square holds 360 degrees, whereas a triangle only holds 180 degrees. A square has all four sides even with 90 degrees in each whereas a triangle angles/sizes vary.
How do you trisect a square into 3 using a triangle?
The Triangle must have a base the dimension of the side of the square, the hypotenuse must also be the same length as the side of the square. Then lay the triangle onto the square so the base is exactly over one side of the square and the opposing point is touching the squares opposite side. The triangle covers 1 of the segments of the square and the uncovered parts make up the other 2. Am I even close?
What is a triangle called where all three angles are 60 degrees?
For one thing, it's an "acute triangle" because all three of its angles are acute. But in the very special case where all three angles are 60 degrees each, the triangle's sides are also all the same length, and that characteristic is the root of it's name. It's called an "equilateral" triangle, even though it's also an "equiangular" triangle.
What do a trapezoid and a triangle make?

Which is the odd one out of triangle square or hexagon?
Triangle: The other shapes have an even number of sides. Square: The numbers of sides on the other two is divisible by 3 Hexagon: For sides of a fixed length, the other two shapes are rigid structures (the square can distort to a rhombus but then it is no longer a square.) or Triangle: It can have all acute angles. Square: It can (must ) have all right angles. Hexagon: It can have all obtuse angles.
Why can you use square units in a circle even tho it is not a square?
For the same reason that you use square units for the surface area of a sphere even though it's not a cube.
