SIMPLE FIGURES
The main plane geometric figures are: CIRCLE The circle is a figure that is made by plotting a curve that is always at the same distance from a point that we call center. The line that borders the circle is called circumference. TRIANGLE The triangle is a figure that is formed by 3 straights that are called sides. There are different ways to classify the triangles, according to their sides or angles. According to its angles: Rectangle: It has a right angle, i.e., it measures 90 º Acute: It has 3 sharp angles, i.e. they measure less than 90 º Obtusangulo: It has an obtuse angle, i.e. it measures more than 90 º According to its sides: Equilateral: The 3 sides measure the same Isosceles: It has 2 equal measuring sides and another uneven Scalene: It has no equal side RECTANGLE The rectangle is a figure formed by 4 straights called sides.
