[u]Ray:[/u] a line that has a point at on end and goes on infinitely in the other direction[br][u]Angle:[/u] Is made up of two rays with two sides that meet at a vertex[br][u]Vertex:[/u] the point were two rays meet to create an angle[br][u]Sides[/u][b][u]:[/u] [/b] Each ray is that makes up an angle is considered a side[br][u]Right angle:[/u] two rays that meet to form 90 degrees[br][u]Acute angle:[/u] two rays that meet to form less than 90 degrees[br][u]Obtuse angle:[/u]Two rays that meet to form more than 90 degrees[br][u]Contingent angle:[/u]Two angle that have the SAME measure[br][u]Angle Bisector:[/u] A ray, line, or line segment, that divides an angle into two equal parts
What kind of angle is the above angle?
Move point A in the angle above to create an obtuse angle
To name an angle, 3 points need to be included. One point from either side and the vertex. The vertex is always the middle point.
How do you name the above angle?[br][br]Select all that apply
[u]Midpoint:[/u] the point on a segment that is halfway between the segment endpoints[br][u]Segment Bisector:[/u] any segment line or plane that intersects a segment at it's midpoint[br][u]Perpendicular Bisector:[/u] any segment, line, or plane that interests a segment and creates a right angle [br][u]Distance of coordinates:[/u] when finding the distance of coordinates you will find the distance of x and of y[br][u]Distance between two points:[/u] when finding the distance between two points you use the distance formula.
Using the distance formula. What is the distance between the two points above?[br][br]Show your work in the box below using the f(x) button **if it is available**[br]Round your answer to the nearest thousandth (3 decimal places)
Explain why and show how to fix your work
What is the distance between the coordinates? (distance between x values and y values?)
