##### Down

**1.**is a type of triangle with at least two equal sides and two equal angles.**3.**Is an angle that measures less than 90 ° and they are in figures like equilateral triangles.**4.**It is a 3d shape that is considered a regular solid shape with six faces with 8 vertices and its base is a square.**6.**is a triangle that has three sides of equal length or is also known as a regular triangle.**8.**a plane figure with at least three straight sides and angles.**9.**are angles with the same measure.**10.**angle that measures exactly 90º.**11.**is the point where two or more elements meet, such as lines, rays or segments.**15.**is the total length or sum of all the sides of a shape, to find it on a rectangle or square, you add the lengths of all the four sides.**17.**figure with four equal sides and four right angles. (Belongs to polygons because its four equal sides whose vertices form 90-degree angles)
