The sum of the side lenghts of a closed plane figure?
perimeter
What is sss in postulate?
This stands for side-side-side. It means if two triangles have three sides that are the same length, than they triangles are congruent.
What else must you know to prove the triangles congruent by SAS?
Nothing. If a side ,an angle, and a side are the same the triangles are congruent.
How do you prove triangles similar?
To prove that two or more triangles are similar, you must know either SSS, SAS, AAA or ASA. That is, Side-Side-Side, Side-Angle-Side, Angle-Angle-Angle or Angle-Side-Angle. If the sides are proportionate and the angles are equal in any of these four patterns, then the triangles are similar.
What is any side of a triangle called?
The sides of triangles do not have set names, except in the case of the right triangle (where one side opposite the right angle is called the hypotenuse). They are usually labelled arbitrarily a, b and c.
How do the ratios of side lenghts compare for triangles that are not similar?
There are no ratios that can be used for triangles that are not similar.
Two triangles that have the same side lenghts will always be congruent?
TRUE
What triangles have sides that are different lenghts?
scalene triangles
What are the names of all triangles and their definitions?
What is the names of all the triangles?
The sum of the side lenghts of a closed plane figure?
perimeter
What is the name of the shape with 4 sidesbut different side lenghts?
quadrilateral
Why all squares are not congruant?
Congruent means they have the same angles and side lenghts. All squares have the same angles (all at 90*) but not all the same side lenghts; a square can be 5x5x5x5 and another can be 6x6x6x6.
What do you called 3 side of polygons?
The sides of a polygon do not generally have specific names. Polygons with 3 sides are triangles.
A regular polygon must have equal side lenghts and equal angles?
true
How do you make 10 triangles with 5 toothpicks?
form triangles side by side
Will side lenghts 6in and 6in make a triangle?
Only if the 3rd side is equal or less than 6in
Are the side faces of a pyramid triangles?
yes they are triangles
