Trigonometry
What is the formula for Sine?
Opposite/Hypothenuse
What is the formula for a Inscribed Circle?
Angle = 1/2 Arc
What are the properties of a Non-Isosceles Trapezoid?
- Only ONE pair of opposite sides are parallel
- Consecutive angles between parallel lines are supplementary
What is the formula for the Phythagorean Theorum?
Both pairs of opposite sides are parallel and equal in length. Opposite angles are also equal. What is Quadrilateral?
Parallelogram
What is the formula for Cosine?
Adjacent/Hypothenuse
What is the formula for a Central Circle?
Angle = Arc
What are the properties of a Isosceles Trapezoid?
- Non-parallel sides (legs) are congruent
- Diagonals are congruent
- Base angles are congruent
- Opposite angles are supplementary
What does the Pythagorean theorem apply to?
It only applies to right-angled triangle
A special type of parallelogram where all four angles are right angles. What is the Quadrilateral?
Rectangle
What is the formula for Tangent?
Opposite/Adjacent
If the central angle for a central circle is 21 degrees, what is the measurement of that angles arc?
21 degrees
What is the area of a Trapozoid?
A = (b1 + b2/2) h
Who discovered the Pythagorean Theorem?
Phythagoras
A parallelogram with all four sides equal in length. Diagonals intersect at right angles. What is the Quadrilateral?
Rhombus
How can you remember the trigonomic formulas?
SOHCAHTOA
Describe the tangent of a circle.
A tangent to a circle is a straight line that touches the circle at exactly one single point, known as the point of tangency. It never enters the circle's interior.
What is the Midsegment of a Trapazoid?
The midsegment of a trapezoid (also called the median or midline) is the line segment that connects the midpoints of its two non-parallel sides (legs)
When was the Pythagorean Theorem dicovered?
570-495 BCE
The most specific quadrilateral, possessing the traits of both a rectangle and a rhombus. It has four equal sides and four 90 degree angles. What is the Quadrilateral?
Square
How many trigonomic formulas are there?
Technically, 6
Describe the chord of a circle.
A chord in a circle is a straight line segment that connects any two points on the circle's circumference. Every point on the chord lies entirely inside the circle.
Of the Isosceles Trapezoid: If AB=14 and DC=26, find EF.
EF = 12
What is the definition of pythagorean theorem?
The Pythagorean theorem is a fundamental rule in geometry that states the square of the hypotenuse is equal to the sum of the squares of the other two sides. It applies only to right-angled triangles.
A quadrilateral with two pairs of adjacent, equal-length sides, but with no parallel sides. What is the Quadrilateral?
