Introduction to The Pythagorean Theorem
We've all heard of it in one context or another. It's the method we use to find the third leg of a right triangle, known as the hypotenuse.
If you are given any two legs of a right triangle (a triangle with one
right angle) you are able to find the third. a and b represent the... | 677.169 | 1 |
But if you instead want to fit the original points into a rotated rectangle then you would have to rotate the rectangle by the negative of that angle.
The image below shows the face from your question together with a plane rotated by −50.005 degrees instead.
If you're also interested in the optimal size of the rectang... | 677.169 | 1 |
How Many Squares
I do not have correct answer, I guess 65. what about yours?
In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or right angles). It can also be defined as a rectangle in which two adjacent sides have equal length. A squa... | 677.169 | 1 |
Central Angles
A central angle in a circle is an angle whose vertex is at the centre of the circle and whose sides (radii) extend to the circumference. It is always measured in degrees and is closely linked to the arc it intercepts. Remember, the measure of a central angle is equal to the measure of its intercepted ar... | 677.169 | 1 |
3. How many sides does a regular polygon have if the measure of an exterior angle is 24°? Solution:
Each exterior angle = sum of exterior angles/Number of angles
24°= 360/ Number of sides
⇒ Number of sides = 360/24 = 15
Thus, the regular polygon has 15 sides.

So I'm wondering if there is a more efficient way to do the above? I know I don't need the hypotenuse and crap (will remove those extra things), but I'm wondering about different techniques all together. | 677.169 | 1 |
This is for a real life situation not a theoretical one. I'm trying to check if a point exist in a Segment of a 2d circle. In other words, I need to know if a given point P(x,y) is anywhere inside the blue part of the circle (see image below).
Given
The radius, the center $(x, y)$, point $A(x,y)$, point $B(x,y)$. The ... | 677.169 | 1 |
Congruent vs. Equal
What's the Difference?
Congruent and equal are two terms used in mathematics to describe the relationship between geometric figures or numerical values. While they may seem similar, there is a subtle difference between the two. Congruent refers to figures or shapes that have the same shape and siz... | 677.169 | 1 |

8. Now suppose the measures of the sides of a right-angled triangle to be p, q, r respectively, the right angle being subtended by that side whose measure is r.
Then since the geometrical property of such a triangle, established by Euclid 1. 47, may be extended to the case in which the sides a... | 677.169 | 1 |
Congruent Triangles
How is being "equal" different from being "congruent" in Geometry? When talking about shapes, we can say that one side is equal to another or the respective angles are equal: this term works well when talking about lengths or another numeric value. If you say, 'These two triangles are equal,' you'r... | 677.169 | 1 |

This is not always true. In a trapezium, opposite sides are not necessarily congruent unless it is an isosceles trapezium. An isosceles trapez... | 677.169 | 1 |
