What else can I help you with?
A tangent line is a line that intersects a circle at exactly two points?
No. A tangent touches the circle at exactly one point. A line that intersects a circle at exactly two points is a secant.
How many planes can contain a line and a point not on the line?
exactly 1
A secant line is a line that intersects a circle at exactly one point?
false
A line and a point not on the line lie in exactly one plane?
True.
Does a rectangle have exactly one line of symmetry?
No, it has two.
Every line has exactly one midpoint?
Yes
What are the slope and yintercept of line 5x 10y 15?
Without the inclusion of an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be a straight line equation
How many lines parallel to AB contain B?
Every line that's exactly on the AB line.
How do you write an equation of a line that passes through the xintercep and yintercept?
You can write it either in standard form (ax + by = c) or in slope-intercept form (y = mx + b)
Does every angle have a vertex?
Every angle has a vertex. A vertex is simply the line through the center of each angle. The line splits the angle exactly in half.
For every line segment there is exactly one midpoint?
Yes. It is a theorem. To prove it, use contradiction.
Does circles has exactly 2 lines of symmetry?
A circle has infinitely many points of symmetry. Every straight line that passes through the center of a circle is a line of symmetry.
What is A line and a point not on the line lie in exactly one plane?
It is a Geometry Theorem. "A line and a point not on the line lie in exactly one place" means what it says.
A tangent line is a line that intersects a circle at exactly two points?
No. A tangent touches the circle at exactly one point. A line that intersects a circle at exactly two points is a secant.
What is it when the moon and earth are exactly in line?
The moon and earth are always exactly in line; any two points define a line. When the earth moon and sun are all exactly in line, that is different. When this happens it is either a solar eclipse or it is a lunar eclipse.
What is the xintercept for 5x - 4y equals 18?
To find the x-intercept for 5x - 4y = 18, plug in a 0 for the y value and solve for x. 5x - 4(0) = 18 5x = 18 x = 18/5 or 3.6 The line will hit the x-axis at (3.6,0)
Are line may intersect a circle at exactly one point?
A tangent line touches the circumference of a circle exactly at one point.
