How many lines of symmetry do right-angled triangles have?
1 line of symmetry.
What congruent shape can 2 right-angled triangles make?
Isosceles triangle
What shapes can be made out of right angled triangles?
Scalene triangles, rectangles, rhombi, concave polygons with 5 or more sides.
Does a right-angled triangle have any equal sides?
A right-angled triangle can have equal sides, but does not have to. A right-angled triangle with two equal sides CANNOT be an equilateral triangle. A right-angled triangle cannot be an equilateral triangle.Divide a square along the diagonal, and you are left with two right-angled triangles with two sides of equal length.
How do you use two right angled triangles to make a parallelogram?
If they are congruent right angle triangles then just join them together side by side to form a parallelogram.
How is trigonometry applied?
Trigonometry is applied in construction and building, as trigonometry measures right angled triangles.
What kind of triangles can the Pythagorean theorem be applied to?
Any right-angled triangle
Who are the famous mathematicians in trigonometry?
Pythagoras was the most pivotal mathematician in the area of trigonometry. His pythagoras theorem literally redefined the way people studied right angled triangles.
How is trigonometry useful?
Trigonometry is useful in buliding, amongst other professions and industries. Trigonometry is a branch of mathematics that deals with triangles, specifically right-angled triangles. It can be used to measure the angles of a triangle as well as all three sides, as long as two measurements are given.
Which triangles have a right angle?
Right angled triangles!
Are all right-angled triangles congruent?
No.Examples:The right angled triangles {3, 4, 5} & {6, 8, 10} are similar;The right angled triangles {3, 4, 5} & {5, 12, 13} are just two right angled triangles.
Why don't triangles have right angles?
Right angled triangles do!
Which congruence theorem guarantees that right angled triangles are congruent?
The checking for right-angled triangles is RHS:Right angle - they both haver a right angleHypotenuse - the hypotenuse of the triangles are congruentSide - a corresponding side of the triangles are congruent.
What are the 7 types of triangles?
The seven types of triangles are Isosceles, equilateral, scalene, equiangular, acute-angled, obtuse-angled, and right-angled
What sort of triangles does pythagoras's rule work in?
Right angled triangles.
What does the pythagorean theorem apply to?
right angled triangles
How many right angles in a cuboid?
