What are the 5 shortcuts used for proving triangles are congruent?
I only know 3. SSS (side/side/side) -> if all three sides are the same length SAS (side/angle/side) -> if two sides and the angle between them are the same ASA (angle/side/angle) -> if two angles and the side between them are the same
How you can prove that two triangles are congruent?
In order for 2 triangles to be congruent, it must be true that each pair of corresponding sides are congruent (equal in length) and each pair of corresponding angles are congruent (equal in size). It is not necessary to prove that all three pairs of sides and all three pairs of angles are congruent. If you prove that all the sides are congruent, then the angles must be congruent, too. This is known as SSS, the side-side-side method of proving congruency. There a four basic ways to prove congruency. They are: 1. SSS (side-side-side) Prove that all three pairs of sides are equal in length. 2. SAS (side-angle-side) Prove that two sides and the angle between them are equal. 3. ASA (angle-side-angle) Prove that two angles and the side between them are equal. 4. AAS (angle-angle-side) Prove that two angles and a side that is NOT between them are equal. Note that you cannot prove that triangles are congruent with AAA or SSA. Note: for right triangles we can use HL. This is a special method that just looks at the hypotenuse and the leg of one triangle and compares it to the hypotenuse of the other. However, if they are both right triangle, the angle between the hypotenuse and the leg is a right angle so this is really just a special case of AAS that we can only use for right triangles.
A line connecting all points along the same longitudinal angle is called a?
meridian
What are two endpoints and all of the points between them called?
A line segment (sometimes just segment) is a pair of endpoints and all the points on a line between them.
What size and shape do two congruent triangles have?
to be congruent two triangles have, ASA-two angles the same with a side length between them. SAS-two side lengths the same and a same angle between them. SSS-all 3 side lengths the same. RHS-if the triangles are right angles ,and the hypotenuse are the same. :)
What is the set of all points between the sides of an angle?
corner...?
How many points must be selected to measure an angle?
To measure an angle you must take all the points in between the two. Therefor it could be anywhere from 2 to 100 points.
Why rainbow is round?
Because from every point on the rainbow, the angle between the direction to thesun and the direction to your eye has to be the same angle. The only collectionof points that can do that is all the points on a circle.

The set of all points outside an angle?
exterior of the angle
Why aren't rainbows staight?
Because at any point IN the rainbow, the angle between the direction to the sun and the direction to your eye has to be the same angle. The only bunch of different points there can be that will do that is a bunch of points that are all on the same circle.
What are external angles?
An external angle is the angle between the outside of one side and the extension of the adjacent line. They all add to 360o.
How many side in obtuse angle?
All angles are made up when two lines or sides vertexes or intersection points, I think.
How do you find the side length on a triangle with one angle given?
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
Why does a Rainbow appear to be bent in a semicircle way?
Because at every point IN the rainbow, the angle between the direction to the sun and the direction to your eye has to be the same angle. The only bunch of points that can satisfy that requirement is a bunch of points that are all on the same circle.
What is angle side angle prostulate?
If 2 "corresponding" angles of two triangles and the side between the two angles are equal, then the two triangles are congruent. This means all their "corresponding" sides and angles are equal.
