Geometry Flashcards
- On a triangle where would you find the smallest and biggest angle to be opposite of?
- If we have a triangle with side lengths of 7 and 14, using the triangle inequality rule which could be the perimeter from the following : 22, 33 or 44
- The biggest angle is always the opposite longest side and the smallest angle is always opposite the smallest side
2.
What do these angles add up to?
- Complementary
- Supplementary
A. What is the Pythagorean Theorem and formula
B. What type of triangle does the Pythagorean theorem only work on?
In the triangle like the one below:
(1) what must you do when it has large values
(2) workout the length of RS
(1) Find the GCF and scale factor it down and solve missing side . Once solved multiply the value by the scale factor to get the suitable answer
(2)
Give two examples of Pythagorean triples
Give 5 Main types of Quadrilateral’s and their properties
What are the properties of a isosceles trapezoid
What is the area of the following:
- Square
- Rectangle, Rhombus, Parallelogram
- Trapezoid
How would you solve slanted shapes like the ones below, when questions ask you to find missing lengths and areas?
(1) What is the formula for the area of a equilateral triangle?
(2) What type of triangle does the equilateral triangle become when you split it in half?
(1) What is the ratio for the sides of a 45-45-90 triangle?
(2) what type of triangle is the 45-45-90 other than a right triangle?
(2) 45-45-90 triangle is also a isosceles triangle
1
What is the ratio for the sides of a 30-60-90 right triangle
If you cut a square in half diagonally what type of right triangle will it form?
It forms 2 isosceles triangles or 2 45-45-90 right triangles.
(1) What is the formula for the interior and exterior angles of a polygon
(2) what is the formula for the interior angles of a REGULAR polygon
(1) Interior angles = 180 x (N-2)
Exterior angles = N/360
(2) Interior angles of Regular polygon = 180 x (N-2)/N
