What is 8x8 rectangle?
An 8x8 rectangle is either a square, all of whose sides are 8 units long or it can be a rectangles whose opposite sides are 8 units long - but in different measurement units: for example, a rectangle whose sides are 8 centimetres and 8 metres.
What is the area of a triangle if all the sides are 6 units long?
9*sqrt(3)= 15.588 sq units (to 3 dp)
Do all triangles have one hypotenuse and two sides?
No, only right triangle has one hypothenuse and two sides.
How do you find the two shorter sides of a triangle when all you know if the hypotenuse and nothing else?
If it has an hypotenuse then it is a right angle triangle and if you know its angles then use trigonometry to find its other two sides.
How do you use the area of a square to find the hypotenuse?
The area of a square is the square of the side (all sides of a square are of equal lengths). So taking the square root of the area would give the value of one side in linear units. Now adjacent sides of a square form a right angle. Therfore the hypotenuse would be the square root of (side^2 + side^2) but you know the value of the side from the previous step when you took the square of the area. Hence you can find the hypotenuse.
How do you find the length of the sides of a right triangle given the hypotenuse?
You can't. You need some more information. If you only know the length of the hypotenuse, you can draw an infinite number of different right triangles that all have the same hypotenuse.
How do you find sides of right triangle given only the hypotenuse and all angles?
One is the hypotenuse times the sine of one acute angle, the other, the hypotenuse times the sine of the other acute angle (or the cosine of the first).
What are the good points to the Pythagorean theorem?
Pythagorean theorem: Usually revolves around the hypotenuse side of a triangle [The side opposite the right angle]. What you do is, You look at the length of all the sides. If Side A [the hypotenuse] Is 8cm long, side B is 3 cm long and side C is 4 cm long. Then what you do is, use this rule. A squared = B squared + c squared. Which basically means, get the lengths of the two sides that are NOt the hypotenuse. Square them. Add them together. Then square root your answer. For example, the answer to: If Side A [the hypotenuse] Is 8cm long, side B is 3 cm long and side C is 4 cm long is: 8x8=64. 3x3=9. 64+9=53. Square route of 53 = 7.28 [rounded] So basically, Square B and C, add them together, square root it to get the length of the hypotenuse
What is the length of the hypotenuse of a right triangle where the two sides are 9 units and 12 units long?
The length of the hypotenuse will be 15 units. The rule is that the sum of the squares of the two sides will equal the square of the hypotenuse. The sides are 9 and 12, and the squares are 81 and 144 respectively. They sum to 225, and that's the square of the hypotenuse. The square root of 225 is 15, and that's the number of units that is the length of the hypotenuse. There are some right triangles that have all sides with lengths in integers (counting numbers or "whole" numbers). They include a 3, 4, 5 triangle, a 5, 12, 13 triangle, and a few others. The thing is, any time you have a right triangle like one of these, a multipleof the lengths will also be a valid right triangle. For the 3, 4, 5 triangle, if you multiply each side by 2, you'll get a 6, 8, 10 triangle. This "new" triangle will obey the Pythagorean theorem. In the 3, 4, 5 triangle, 32 = 9, 42 = 16 and 52 = 25; and 9 + 16 = 25 so it checks. Same with a 6, 8, 10 triangle. In that one, 62 = 36, 82 = 64 and 102 = 100; and 36 + 64 = 100, so that checks as well. Why'd we go through that? Check this out. If we take a 3, 4, 5 triangle and multiply all sides by 3, we'll get a 9, 12, 15 triangle. Do those numbers look familiar? They are eerily similar to the ones in the question.
What is the perimeter of a pentagon with sides of 63?
To find the perimeter of a pentagon with sides of 63 units each, you would simply add up the lengths of all five sides. Since all sides are equal in a regular pentagon, the perimeter would be 63 + 63 + 63 + 63 + 63 = 315 units.
What is the perimeter of a rectangle measuring 8 units on 2 sides and 4 units on 2 sides?
Perimeter is equal to the sum of all sides, in this case 2 of the length of the rectangle plus 2 of its width: 2*8 units +2*4 units ______ 16 + 8 =24 units
What example should i use for a hypotenuse?
A right triangle with sides in length of 3,4, and 5 has a hypotenuse of length 5. It's the best example because all the numbers are whole (integers) and its the smallest of its kind.
