test 1&2 Flashcards
what is a hypotenuse?
The hypotenuse is the side opposite
the right angle in a right-angled triangle.
what are the legs?
The legs of a right-angled triangle are
the two shorter sides that form the right angle
(true/false) the hypotenuse is the shortest side
false, it is the longest.
what is the role of the legs?
Legs are adjacent to the right angle
what are the legs usually denoted as?
Typically denoted as ‘a’ and ‘b’ in the
Pythagorean Theorem.
what is the hypotenuse usually referred or denoted as?
it is often denoted as ‘c’ in the
Pythagorean Theorem (a² + b² = c²),
how to get “c”?
c^2=a^2+b^2
how to get “a”?
a^2=c^2-b^2
how to get “b”?
b^2=c^2-a^2
what is a circle?
A circle is the set of all points in a plane that
are the same distance from a given point called the center of a circle.
what is a radius?
A radius of a circle is a line segment from the center to a point on a circle.
what is a chord?
A chord of a circle is a segment with
endpoints on the circle.
what is a diameter?
A diameter of a circle is a chord that passes through the center of a circle.
what is the circumference?
The circumference of a circle is the distance around the circle.
what is the formula of the radius?
Radius Formula 𝑟 = 𝑑/2 or 𝑟 = 1/2 𝑑
