If you have a circle and the measure of the arc AB equals 80 and the measure of arc CE equals 16 which is the measure of EDC?
32 degrees
The measure of an angle formed by two secants intersecting inside the circle equals?
½ the sum of the intercepted arcs.
Why is the tangent of 45 equals 1?
Let's look at an right isosceles triangle (where the base angles measure 45 degrees, and legs are congruent). So that, tan 45 degrees = leg/leg = 1
Do you measure angles in anything other than degrees?
You can measure angles in degrees. However, The other common measurement for angles is radians. For this measurement, consider the unit circle (a circle of radius 1) whose center is the vertex of the angle in question. Then the angle cuts off an arc of the circle, and the length of that arc is the radian measure of the angle. It is easy to convert between degree measurement and radian measurement. The circumference of the entire circle is 2 ( is about 3.14159), so it follows that 360° equals 2 radians. Hence, 1° equals /180 radians, and 1 radian equals 180/ degrees. Most calculators can be set to use angles measured with either degrees or radians. Be sure you know what mode your calculator is using.
What is the difference between equal and congruent in math?
equals is used when two things are the same value congruent is used when to things are the same size and shape
If you have a circle inscribed in a square what is the diameter congruent to?
The diameter of the circle equals the length of a side of the square
If you have a circle and the measure of the arc AB equals 80 and the measure of arc CE equals 16 which is the measure of EDC?
32 degrees
If the measure of arc XY plus the measure of arc YZX equals 360 degrees and the arcs do not overlap then the arcs form what?
a circle
The length of an arc equals the degree measure of the are divided bt 360 times the?
circumfrence off the circle
The measure of an angle formed by two secants intersecting inside the circle equals?
½ the sum of the intercepted arcs.
A circle equals how many degrees?
A circle equals 360º.
Ab and ac are tangents to a circle with centre o and radius 5cmif ac equals 12cmfind the perimeter of quadrilateral aboc?
Since AB and AC are tangent to the circle O, it seems that they both are drawn from the same outside point A. As tangents to a circle from an outside point are congruent, AB ≅ BC. Also, a tangent is perpendicular to radius drawn to point of contact. So that OB and OC are congruent radii. Therefore, the perimeter of the quadrilateral ABOC equals to P = 2(12 cm) + 2(5 cm) = 34 cm.
How do you measure the area of a circle and why does it work?
The area of a circle is equal to that of a triangle whose base has the length of the circle's circumference (distance around the circle) and whose height equals the circle's radius which comes to Pi multiplied by the radius squared. Area of Triangle 1/2 *base*height
What is the maths symbol for congruent?
It's the equals sign with the ~ above it. ≅
What is circle times circle equals square AND circle triangle divided by square equals circle plus circle?
well it means that if u square something that's is all i know
What else would need to congruent to show that abc equals pqr by sss?
That depends on which sides have not been proven congruent yet.
