What two dimensional figure has opposite side parallel and four right angles but not four equal sides?
The shape can only be a rectangle! A rectangle is a four-sided 2-dimentional figure, where every angle is a right angle, opposite sides are parallel, but the 4 sides are NOT equal.
What is the minimum number of right angles there can be?
That depends on what type of shape it is as for example a triangle can only have 1 right angle of 90 degrees.
How do you know if a triangle is a right triangle using the pythagorean therom?
We know that a right triangle is a triangle having a right angle, where the side opposite the right angle is the hypotenuse, and the perpendicular sides are the legs of the right triangle. The Pythagorean theorem gives the relationship between the lengths of the sides of a right triangles. In the case where you know only the measure lengths of the sides of a triangle, you need to test these measures. If one of the sides of the triangle has a square measure equal to the sum of the square measures of two other sides, then this side is called the hypotenuse and opposite to this side is a 90 degree angle, which is a right angle. So, you can say that this triangle is a right triangle. Pythagorean triple are very helpful to determine a right triangle, such as: (3, 4, 5), (5,12,13), (8, 15, 17), (7, 24, 25), and (20, 21, 29).
Find hypotenuse only using opposite and angle?
In a right angles triangle the sides are named the hypotenuse (the side opposite the right angle) and the other two sides are called the adjacent and the opposite sides. 1) The sine of an angle = length of the opposite side ÷ length of the hypotenuse. 2) The cosine of an angle = length of the adjacent side ÷ length of the hypotenuse. Using 1) The length of the hypotenuse = length of the opposite side ÷ the sine of the angle. Using tables or a calculator obtain the sine of the angle and divide this into the length of the opposite side. The result will be the length of the hypotenuse.
What is the conclusion of pythgoras theorem?
Pythogaras Theorem applies only to right-angled or right triangles. The theorem states that in any right angle triangle, the square of the lenght of the longest ( called the Hypothenuse) equals the sum of the squares of the other sides of the triangle
