Question: I NEED Help With Math!!! GEOMETRY!!!?

use coordinate geometry to prove that the diagonals of a square are perpendicular. please help me… its due tomorrow and i have test so please explain your answer thank you in advance

Answer: because each of the four sides are equal because of the def. of a square, their diagonals are equal. also, since each of the angles of a square are 90, when pythagorean theorem is done on half of half of a square cut diagonally, the angles of the smaller square are 45, 45, 90, 90 being the angle of the intersecting diagonals

Below is a video showing different polygon shapes and names of polygons in geometry. The polygon shapes video starts with defining what a polygon is, then introduces polygon names as well as polygon shapes and types of polygons. You can use this polygon shapes video as part of your lesson plans for polygons. There are regular polygons, congruent polygons, irregular polygons and more.

Polygon Shapes

What is a polygon?

A polygon is a closed planar figure formed by three or more line segments. Polygons are named according to the number of sides they have. Polygons are further defined by the angles between the sides of the polygons as well as the lengths of the sides.

Question: Math Geometry question about terms! its for a crossword! pls help!!?

(the numbers are just for me to not get confused)
ACROSS
13. Point located on the horizontal axis. Example(7,0) ….ten letters
25. figure made up of more than one shape…….nine letters
30. polygon with all sides of equal length….seven letters
32. the line segment of a three dimensional figure….4 letters
36. halfway point on a segment …8 letters
58. four sides polygon…..13 letters
DOWN
1. point located on a vertical axis. Example(0,4)…….10 letters
19. a portion of the Area of a Circle……6 letters
29.the shape on an object before a transformation……..8 letters
43. the distance part of the way around the circle….9 letters
47. three dimesional figure with four faces……11 letters
57. polygon with no congruent sides……7 letters

Answer: ACROSS
13. see last person’s answer…wow could not understand that clue at all lol (x intercept)
25. composite
30. regular or could be rhombus
32. edge
58. quadrilateral
36. midpoint

DOWN
1. see last person’s answer of y intercept
19. sector
29. preimage
43. arc length
47. tetrahedron
57. could be concave or scalene like the last person said (concave quadrilateral/scalene triangle)
