- 3. a triangle in which two sides have the same length. Two sides have the same measure but the other side is different or not congruent.
- 7. All three sides of a triangle have different lengths and measures. All of the sides are unique and different.
- 10. a line that passes through two lines in the same plane at two distinct points. Transversals play a role in establishing whether two or more other lines in the Euclidean plane are parallel.
- 11. used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. The equation is (y-y1)=m(x-x1).
- 15. The theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse. The equation for this is a^2+b^2=c^2.
- 16. This means that a shape, line, or figure has the same exact measure, shape, and size. The lines are identical in measure.
- 17. polygon that has all interior angles that are congruent. All of the angles have the same measure.
- 19. Algebraic expression that gives the distances between pairs of points in terms of their coordinates. This formula is based off of the pythagorean theorem.
- 20. a type of transformation that takes each point in a figure and slides it the same distance in the same direction. It doesnt rotate, flip, or change the size of the figure
Down
- 1. a transformation representing a flip of a figure. The figure is a mirrored image of itself once it is flipped
- 2. a line that intersects another line segment perpendicularly and divides it into two parts of equal measurement. It splits the line segment directly in half which creates two congruent halves.
- 4. the longest side of a right triangle, opposite the right angle. In the pythagoream theorem this represents c^2.
- 5. coplanar straight lines that do not intersect at any point. They are always the same distance apart from each other.
- 6. the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept. It emphasis the slope and the y intercept on the line.
- 8. All sides or faces of a triangle are congruent. All of the sides and faces have the same measure.
- 9. a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point. The rotation goes in a circular rotation around the point.
- 12. the formula to find the center point of a straight line, using the coordinates of its endpoints. The equation is ((x2+x1)/2),((y2+y1)/2 )
- 13. an angle that measures between 90° and 0°, meaning it is smaller than a right angle. They can be found in triangles.
- 14. lines that intersect at a right (90 degrees) angle. These can be found everywhere. For example a four way intersection
- 18. a type of angle that is always larger than 90° but less than 180°. In other words, it lies between 90° and 180°.
