By definition, the area of the surface x is smaller than that of the surface y if: After superposition x lays inside y. It can only be said calculating the two areas. After superposition x lays inside y, or if x is scissor-congruent to surface which lays inside.

Polygons are important surfaces because: There are polygons of any number of sides. They are the reason so to studey the magnitude amgular amplitude. They can be used to fill curvilinear surface whose amount of area is difficult to calculate.

To carry out a direct comparison of the angles α and β: We measure the two anfles and then we compare the corresponding numbers. We superpose one of the segments of the angle α with the corresponding segment of the angle β. We first need to check whether they are corresponding angles in parallelism situation.

By definition, an obtuse angle is an angle such that: It is bigger that a right angle. It is bigger than a right angle and smaller than a flat angle. It is part of an obtuse triangle.

By definition, two angles are opposite if. They are equivalent respect to magnitude angular amplitude. They share the vertex. They add up zero angle, that is to say, the smallest possible angular amplitude.

By definition, two surface are congruent if: They have the same shape and the same size. They have the same amount of area. One of them can be cut into pieces that can be ressembled to yield the second.

By definition, a rectangle is. Never a square. A quadrilateral with right interior angles. Never a parallelogram.

If two segments are parallel, they are always at the same distance, even when enlarged, because: As shown by using the criterion angle-side-angle, any two straight segments joining r and s in a perpendicular way have the same amount of length. The segments r and s do not meet when enlarged. Otherwise, the segments r and s, when enlarged, would be parallel only in some sections.

To carry out an indirect measurement of the area of a rectangle one has to multiply the amounts of length of two adjacent sides because: One of those amounts of length can be regarded as telling you the number of units of measure are needed to fill a row, and the other amount of length can be regarded as telling you how many rows are. One of those amounts of length can be regarded as telling you the number of units of measure are needed to fill a row, and the other amount of length can be regarded as telling you how many columns are. One of those amounts of length can be regarded as telling you the number of units of measure are needed to fill a column, and the other amount of length can be regarded as telling you how many rows are.

In an acute triangle. One height is always bigger that the other two. The three heights lay inside the triangle. Only one of the angles need to be acute.
