### Circle scribe

Hey again

This is post is for today's class

today we wrote in our math journals most of the class and then we did a circle geomerty that we have to finish tonight for homework. This post was edited Nov 23 at 5:45**Circle Geomerty****fundamentals**

1) The sum of all angles in a triangle is 180^{0}

2)the angle exterior to a triangle is equal to the sum of

the opposite interior angle

3)**Congruent:** Means the same shape and size

4)**Transversal:** A line intersects 2 parallel lines

5)**Opposite angles:** two angles that are opposite

each at the intersection of to two lines are called opposite angles.

opposite angles are congruent

6)**Alternate angles:** two angles on alternate sides of a transversal are

called alternate angles. They are congruent **7) Corresponding angles:** two angles on corresponding sides of a

transversal are called corresponding angles. They are always congruent.

8) **Congruent Triangles:** any two triangles can be proven congruent using

one of these four properties .**The Anatomy of a Circle**

O - is the centre of the circle

is a chord- A straight line that joins two points on the circumference

is a diameter - chord passing through the center of a circle.

is a sector - a lime segment that contains a chord

is a tangent- a line that intersect, (touches) the circle at one point

radius- a straight line that joins a point on the circumference to the centre

is a minor arc- part of the circumference

is a is a major arc some but bigger

**segment AB**- part of the area of a circle bonded by a core and a minor arc

**Sector FOC**- part of the area of a circle bonded by the centre angle and an arc

**centre angle:**angle whose vertex lies on a circumference of a circle.

**Inscibed angle**: A angle whose vertex lies on the circumference of a circle

**"Arc":**the measure of an arc is equal to the measure of the centre angle that subtends that arc

This is all the notes I got I think I Missed a couple on the board sorry. If anyone has the rest please send me a comment and tell me so I can edit the post thanks. Thanks Robert for letting me borrow your notes

Tomorrows scribe will be ....... larisa
