How are a square and a Pentagon alike?

How are a square and a Pentagon alike?

A square is a polygon that has 4 straight sides that are all the same length. A square also has 4 angles that are all the same size. A pentagon is a polygon that has 5 sides and 5 angles.

How are triangles and squares alike?

They are both polygons. They are closed shapes in two dimensions with straight lines as edges. If the triangle were equilateral, they would both have sides of equal length and each would have internal angles of equal size (90 and 60 degrees respectively for square and triangle).

Is a triangle A Pentagon?

If we divide a pentagon into triangles as in the figure on the left below, the pentagon is made up of 3 triangles, so the angle sum is 180 + 180 + 180 = 3*180 = 540 degrees. However, the non-convex pentagon on the right is a trickier case….Angles in Isosceles Triangles.

What do a triangle and a hexagon have in common?

Answer and Explanation: Triangles and hexagons have some commonalities because both are polygons. Polygons are two-dimensional closed shapes. The sides of a polygon must be…

What does a triangle and a circle have in common?

Two triangles in a circle are similar if two pairs of angles have the same intercepted arc. Sharing an intercepted arc means the inscribed angles are congruent. Since these angles are congruent, the triangles are similar by the AA shortcut.

What do triangles have in common?

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

What do the tick marks on a triangle mean?

Little tick marks are used to show that two sides are the same length (congruent). You can use just one tick mark, two or three or more — just as long as you use the same number on sides that are equal. Notation for congruent angles in a triangle: This works a lot like congruent sides (above)…

What does a line through a side of a triangle mean?

The dashes on the lines show they are equal in length. The angles at the base of the equal sides are equal. An equilateral triangle has 3 sides of equal length. The dashes on the lines show they are equal in length. All of the angles are also equal.
