Obstruction Angle Example

 A Obtuse angle is the one who it measures more than 90 °. It usually manifests itself in the following geometric figures:

Scalene triangle. In the illustration, the obtuse angle measures 135 °.

Isosceles triangle. In the illustration, the obtuse angle B has such a measure that angles A and C are equal, and between the three they give the sum of 180 ° of the triangle.

For example, B can measure 100 °, and the other 40 ° each.

B can measure 120 °, and the other 30 ° each.

B can measure 140 °, and the other 20 ° each.

B can measure 160 °, and the other 10 ° each.

The result would be that the sides of the triangle would extend to form the smallest angles.

ANY triangle that has an obtuse angle is also called an obtuse triangle.

Diamond. It is a geometric figure that consists of four equal sides, between which no right angle is formed, as in the square. This consists of two obtuse angles, and two acute angles.

Rhomboid. It is a geometric figure that consists of four sides: Two long and two short sides. The sides of equal measure are parallel. This figure consists of two obtuse angles and two acute angles.

In the Trapezium isosceles, there are two sides equal to the sides, a minor base and a major base. The bases are parallel. The sides generate two equal obtuse angles and two equal acute angles.

In the rectangle trapezoid, only one angle is obtuse. There are also two right angles, and one acute. The top and bottom sides are parallel.

When studying angles in geometric figures with more than four sides, the beginning is always the center. The sides of the pentagon are represented by the bases of five imaginary triangles whose upper vertices converge in the center. If we divide the 360 ​​° base by 5 sides of the pentagon, the result is 72 °. That corresponds to the vertex that is in the center. What is left to complete the conventional 180 ° of a triangle is 108 °. That should measure the sum of the two remaining angles of the imaginary triangle. Thus it follows that it is what an internal angle of the Pentagon should measure. We gather the lower vertices of two contiguous triangles. This is the case with the other geometric figures with a greater number of sides.
