Geometry Stuff And More

1. The trig function cosine, which is written cos θ. Also known as cos
4. And let Two angles that add up to 180°.
6. A theorem relating the way three concurrent cevians of a triangle divide the triangle's three sides.
9. Geometry The study of geometric figures using the coordinate plane or coordinates in space. Formulas from analytic geometry include the distance formula, midpoint formula, point of division formula, centroid formula, area of a convex polygon.
13. A geometric figure in three dimensions excluding interior points, if any.
16. 3.14 and so on. Irrational number.
17. The shortest distance between the base of a geometric figure and its top, whether that top is an opposite vertex, an apex, or another base.
18. =180 degree angle. Equals up to a triangle, but not one.

1. Has six sides on it. All the sides are even.
2. When two triangles have corresponding angles that are congruent as shown below, the triangles are similar.
3. The line segment that passes through a triangle’s orthocenter, centroid, and circumcenter. These three points are collinear for any triangle.
5. has four triangles and a square at the bottom. It's located in Egypt.
7. the amount of space inside a shape. Opposite of Perimeter.
8. The study of triangles, with emphasis on calculations involving the lengths of sides and the measures of angles. Trigonometry is also known as trig.
10. Two rays sharing a common endpoint. Angles are typically measured in degrees or radians.
11. The first coordinate in an ordered pair.
12. the amount of space outside the shape. Opposite of Area
14. A tube basically, two circles with a rectangle or square wrapped around
15. (0,0) Part of a coordinate plain
19. The vertex at the tip of a cone or pyramid.
