What is the perimeter of the quadrilateral below?

To calculate the perimeter of a quadrilateral, you need to add the lengths of all four sides. If the lengths of the sides are given, you simply add them together. If the side lengths are not provided, you may need additional information such as angles or diagonal lengths to calculate the perimeter. Without specific measurements or additional details, it is not possible to determine the perimeter of the quadrilateral.

What is the semi-perimeter of a triangle with side lengths 11 61 and 60?

Semi-perimeter means half the perimeter. Calculate the perimeter, then divide that by 2 to get the semi-perimeter.

How do you find the diagonals of a rhombus?

You need more information: the length of a side. Then, since the diagonals bisect one another at right angles, you can use Pythagoras's theorem to calculate their lengths.

Why do you not usually multiply the side lengths of a parallelogram to calculate its area?

To find area you need base and height of a parallelogram. A = BH Not all the side lengths given would be base or height. Side lengths are perfect to find perimeter but don't rely on the side lengths for area.

How do calculators calculate Sin Cos and Tan of an angle without side lengths?

The relationship between an angle and the triangle formed by it is always constant. This is also why sin cos and tan obtained from the unit circle can be applied to all triangles with the same angle. All that matters is the ratio of the sides, so the calculator can "pick" any length for one side, and use that and the angle to find the other side(s). This answer will be the same regardless of which triangle you are specifically referring to. Side lengths 3 and 5 will produce the same trig values as sides 21 and 35. Also, given the processing power of most calculators, these values are often programmed in, similar to how many students are "programmed" to know the trig values for major angles such as pi, pi/4, 30deg, and 60deg.

How to calculate the sides of a triangle given the degree of an angle and one side?

The measure of only one angle and one side is not sufficient to calculate the lengths of the sides of a triangle. If you have one more angle or one more side you can use the sine rule.

How do you classify a triangle with 3 given side lengths?

That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.

How do you find the perimeter of a triangle if only 2 side are given for grade6?

You can't. To calculate another side length you need an angle. you need either two angles and a side length, or two side lengths and an angle to solve for other angles or side lengths. No matter what the case, you need three pieces of information i do not understnd it

What is the measure of each interior angle of a irregular hexagon?

This cannot be answered without any given side lengths, since the interior angles of an irregular hexagon are different. Only the angles of a regular hexagon can be found without side lengths, and that is 120 degrees per angle.

How do you find the length of sides of trapezium?

Which side lengths? To calculate the parallel sides, you need the height of the trapezium and one of the sides, and you substitute them into the formula: h(a + b)/2, where h = height, a and b are the parallel side lengths. If you want to find the sides that are not parallel, you need the parallel sides, as well as the height of the trapezium. Then, by using Pythagoras theorem, with the side length the hypotenuse, you can find their lengths.

How do you calculate the length of the hypotenuse?

The hypotenuse is the longest side in a right-angled triangle.You can calculate this in different ways depending on what pieces of information you have.If you have the lengths of the two shorter sides, you can use Pythagoras.Or if you have a side and an angle then you may be required to use Trigonometry.
