they have at least one right angle.
A square is the union of two isosceles right triangles. The hypotenuse of each triangle is the diagonal of the square.

What shapes have right angles?
squares, right triangles, rectangles
Do triangles and squares have parallel lines?
Squares do, triangles don't.
How do you make 2 squares and 4 triangles with 8 straight lines?
See the link under related links below that says "8 Lines 2 Squares 4 Triangles"
Do triangles and squares have right angles?
A square has 4 right-angles. A right-angle triangle has 1 right-angle
Are all squares triangles?
No because squares have 4 sides whereas triangles have 3 sides
What is the ratio of squares to triangles?
1:2
Are squares triangles?
yes they are
Is all squares can be cut in half to make 2 congruent triangles a generalization?
no its an emphatic statement all squares can be cut in half to make 2 congruent isosceles right triangles is perhaps as general a statement as is possible
Are right triangles squares?
No because a square fas 4 sides whereas a triangle has 3 sides
Will a pattern of right triangles and squares tessellate?
Yes. Consider the situation when: the right-angled triangles are also isosceles and the hypotenuse (longest side) of the triangles is equal to the side of the square. If you surround a square with four of right-angled triangles (the sides of the square being in contact with the hypotenuses of the triangles), you get a larger shape which is also a square. Taking this as a basic unit, you can make a tesselations. You can also make tessalations if you have two sets of squares, one with sides the same length of the hypotenuse of the triangles and one with sides the same length as the smaller sides of the triangles.
What are small squares on a selected rectangle?
The small squares are indicators that the angles are right angles, which are found in shapes such as rectangles, squares and right-angled triangles. A right angle is 90 degrees, 1 quarter of 360 degrees, a full turn, such as a circle. I hope this helps ^^
What shapes contain right angles?
Squares, rectangles, and some triangles, most commonly. Any polygon could have a right angle if it is irregular.
