Right angle: One of the special categories of angles

 In very simple terms kids need to note down that the right angle is the angle that will be exactly equal to 90° or the value of pi/two in measure. There are several kinds of real-life examples in the cases of right angles for example corner of the book, the edges of the cupboard and several other kinds of related things. Any shape that is a square or rectangle will be having corners equal to the 90° or the right angle and hence right angle is also known as a 90° angle. 

 Angles that have been perfectly created by two lines into the plane will be consisting the lines at the intersection of two planes will always help in the formulation of the angles. Angles can be perfectly used in terms of designating the measure of the angle or the rotation without any kind of issue and further being clear about several kinds of categorisation is important.

 Some of the real-life examples are:

  1. L-shaped sofa
  2. Corner of the book
  3. Corner of the laptop
  4. Edge of the window or door
  5. Corner of the wall and several other kinds of related things.

 The right-angle triangle will be the one that will be having three sides which will be namely perpendicular, hypotenuse and the base with the angle between the base and perpendicular will be 90°. The right-angle triangle is one of the basic possible shapes in the world of mathematics and is also known as the foundation of the world of trigonometry. Kids need to be clear about different kinds of right angle formulas as well and the most important formula can be termed as the Pythagoras theorem over here which has been explained as:

 Hypotenuse Square = base square + perpendicular Square

 Some of the very basic properties of the right angle triangle have been explained as follows:

  • The right-angle triangle will be having exactly one angle equal to the 90°
  • Angles other than the right angle must be acute angles which makes sure that they will be less than 80°
  • The side opposite to the vertex of 90° will be known as the hypotenuse of the right angle and this is the longest possible side of the triangle
  • The other two sides will be at the centre to the right angle and will be known as the base and perpendicular
  • The circumflex circle of the right triangle will be passing through all three vertices as well as the radius of the circle will be equal to half to the length of the hypotenuse.
  • Kids need to be clear about the formulas associated with the right triangle which will be area and perimeter. The area will be the same half into base into height and the perimeter will be some of all the three sides without any kind of doubt in the whole process.

 Apart from this when two sides other than the hypotenuse will be congruent into the right triangle it will be known as the right-angled Isosceles triangle or simply the isosceles right triangle. In this particular case of the triangle, the angles will be made by the base and perpendicular with the hypotenuse will be congruent because both of them will be measuring 45° each. It is very much important for kids to be clear about real-life examples in this area so that there is no chance of any kind of issue in decision making. Hence, depending upon the platforms like Cuemath is the best possible way of having a good command over different types of angles like obtuse angle, acute angle and several other kinds of available options in the industry.
