Acute angle
Angles whose measures are less than 90°.
Take into account that the acute angle must not be zero (0°), therefore we have:
Let «α» be the acute angle, then it is fulfilled:
0°<α<90°
notice the figure of an acute angle:
Examples of the Acute Angle
Next, we will see several examples of acute angles. Let’s see the following:
30°, 12°, 45°, 65°, 60°, 30°, 15°, 89°, 18°, 5°, 75°, 30.5°, 37°
We can also say that we see the acute angle in geometric figuresLook at the figures:
1. Acute Angle in a Rhombus
In a rhombus we have 2 acute angles, they are seen at the opposite vertices. I watched:
2. Acute Angle in Equilateral Triangle
In a equilateral triangle we have 3 acute angles equal to 60°. I watched:
3. Acute Angle in daily life
Other examples of acute angles we see in daily life, in many objects and things, let’s see 2 illustrative examples:
to. Acute angle in the Egyptian pyramid:
b. Acute angle on a ladder:
