What is the line on top of a circle called?
A tangent is a straight line outside the circle that touches the circumference at one point only. A segment is the area enclosed by a chord and an arc (it looks similar to the segment of an orange or grapefruit).
What is a chord that passes through the center of a circle?
Equal chords are subtended by equal angles from the center of the circle. A chord that passes through the center of a circle is called a diameter and is the longest chord of that specific circle.
What is distance around circle?
The circumference of a circle is the distance around the outside of the circle. It is like the perimeter of other shapes like squares. Given the radius or diameter and pi you can calculate the circumference. The diameter is the distance from one side of the circle to the other at its widest points.
What is a circle notation?
A notation for large numbers due to Steinhaus (1999). In circle notation, is defined as in. squares, where numbers written inside squares (and triangles) are interpreted in terms of Steinhaus-Moser notation.
Which lines are Secants?
A straight line can intersect a circle at zero, one, or two points. A line with intersections at two points is called a secant line, at one point a tangent line and at no points an exterior line. A chord is the line segment that joins two distinct points of a circle.
What is an angle whose vertex is the center of the circle?
A central angle is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B. Central angles are subtended by an arc between those two points, and the arc length is the central angle of a circle of radius one (measured in radians).
Is an angle whose vertex is on the circle?
An angle whose vertex lies on a circle and whose sides intercept the circle (the sides contain chords of the circle) is called an inscribed angle. These secant lines intersect each other at the vertex of the angle. The measure of such an angle is half the sum of the measures of the arcs it intercepts.
Is an angle whose vertex is the center of the circle?
Central Angle: An angle whose vertex is the center of a circle. The measure of a central angle is equal to the measure of its intercepted arc.
What is the distance across the center of a circle called?
diameter
The distance from one side of a circle through the center to the other side is called the diameter of the circle.
What do you call an angle whose vertex is the center of the circle?
A central angle is an angle whose apex (vertex) is the center O of a circle and whose legs (sides) are radii intersecting the circle in two distinct points A and B. The central angle is also known as the arc’s angular distance.
Which lines are Secants Why?
A secant line, also simply called a secant, is a line passing through two points of a curve. As the two points are brought together (or, more precisely, as one is brought towards the other), the secant line tends to a tangent line.
What should I do if my AC drain line is full?
Step 1: Turn Off The Power To Your AC. Turn the power off at the thermostat and at the breaker. Step 2: Find Your AC Drain Line. This is a PVC pipe that is usually situated outside, near your condenser unit. You might require a bucket at this point should your drain line be full. Step 3: Identify The Point Of Access On The Drain Line
What causes an air conditioner drain line to leak?
The method that this water is produced is just like the water that forms on the outside of a glass with ice in it. The warmer air from your home, meets the colder surface of the evaporator coil and naturally, condensation occurs. The bad part happens when you find the air conditioner drain line clogged and a water leak on the floor!
What does it mean when your AC pipes are clogged?
When operating properly, you’ll probably notice a small trickle of water at the end of a PVC pipe outside your home somewhere, which is where the moisture travels. This is where problems occur and may lead to a backlog of water and/or a blockage. Other signs of a clogged AC drain pipe include:
Where does the water from an air conditioner drain go?
Gravity Condensate Drain, where the water flows from your evaporator coil drain pan, directly into a small PVC drain line, and either into a drain system, in or outside your home.
How to seal a hole in an AC unit?
How to seal an AC hole? I just had a central air unit installed and the installers drilled a large hole through the exterior wall to run the lines through. To fill this hole they used the same sealant putty used to seal around the lines into the duct. I don’t think this is right.
