Chap 5 Area/Pythag/Special Right Triangles
What is the Pythagorean theorem?
a^2 + b^2 = c^2
What is a ratio?
A comparison of two numbers
What is the difference between a secant and a tangent line?
Tangnet touches once. Secant touches twice.
When a<b, is ac<bc a true statement? Why or why not?
No, If c is negative or 0
The point (0,0) is called the what?
Origin
Find the value of x
x=40
x+3/6 = 8/12
What is the difference between a central angle and an inscribed angle?
Hey Guys
-x/3 + 4 > 6
x<-6
Draw a Cartesian plane. Label it with numbers, accurate axis names, and quadrants.
hey zeke
Find x, and y
x = sqrt(6), y = 2sqr(3)
Area these 2 triangles similar? Why or why not?
Yes, AA
AB and BC are tangents. Angle 1 = 60. Find the measure of Angle B
B=120
Draw it
Draw it
Through (-1,2), write the equation of a line perpendicular to y=(4/5)x-5
y = (-5/4)x + 3/4
Draw a square and its diagonal. Show that the diagonal is sqrt(2) times as long as the side of the square. (Hinit: Call the sides of the square "x")
Will Vary
Find x
OC is perpendicular to AB. If Angle AOB = 120, find the measure of arc DB.
120
If OF = 8 and OE = 9, which of arc CAB and arc DCA is greater? HAVE TO SHOW WORK here
CAB
See board. Find the point of intersection.
x=-6, y=7
Find the total area.
43pi
Find x.
x = 48/3
Find the measure of angle 1 and angle 2
angle 1 = 80
angle 2 = 40
Prove: The diagonal of a rectangle is longer than any side of a the rectangle.
HEY YOU GUYS
Show, using analytic geometry, that a rectangle has 1 90 degree angle. You can use numbers
