What is an isosceles triangle example?
Some popular examples of an isosceles triangle in real life are a slice of pizza, a pair of earrings. The equal sides of an isosceles triangle are known as the ‘legs. The third and unequal side of an isosceles triangle is known as the ‘base.
What are the angles in an isosceles triangle?
An isosceles triangle is a type of triangle that has two sides that are the same length. The two marked sides are both the same length. The two angles opposite these two marked sides are also the same: both angles are 70°. All three interior angles add to 180° because it is a triangle.
Why is a triangle called a right triangle?
A right angled triangle is a triangle with one of the angles as 90 degrees. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle.
What is a vertex angle in a triangle?
In an isosceles triangle, the two equal sides are called legs, and the third side is called the base. The angle formed by the two equal sides is called the vertex angle.
Which is the corresponding angle to ∠ 1?
∠2 ≅ ∠60° since they are corresponding angles, and m and n are parallel. ∠1 and ∠2 form a straight angle, so∠1=120°.
What is the relationship between angle of insolation?
What is the relationship between angle of insolation and intensity of insolation? The intensity of solar radiation is largely a function of the angle of incidence, the angle at which the Sun’s rays strike the Earth’s surface.
How does the insolation and zenith angle affect the climate?
The climate depends on the insolation and zenith angle averaged over a 24-h period, over a season, and over a year. In this section, the geometric factors that determine insolation and solar zenith angle will be described.
What is the insolation of the solar radiation?
Insolation is the amount of solar radiation received on a given surface in a given time period. In particular, daily insolation Q (MJ m − 2 day − 1) is the solar radiation incident on a horizontal surface per square metre integrated over a day. Insolation varies seasonally and with daily variation in cloud cover.
