## What are the characteristics and uses of an isosceles triangular?

An Isosceles Triangle possesses the following properties:

- Two sides are compatible.
- The base of an isosceles triangular is the third side that is not equal to the two other sides.
- The opposite angles to the equal sides are congruent.

## Why do all isosceles triangles have right angles?

An isosceles triangle can have two sides that are equal in length. Therefore, angles to each side will be equal.

**What is true about the measure of angle B quizlet? **

What is the truth about angle B’s measure? It is equal to angle C. See the diagram for proof. It is clear that B C.

**What is the measure of angle ABD? **

Angles ABD is right angle and DBC is left angle. Angles CBE, DBE and DBE can be described as acute angles. Angle ABE is an obscure angle. The sum of the three angles in any triangle is always 180deg….Click Go On to begin.

Since b is a right angle, b | =90deg. |
---|---|

a | =50deg |

### What is the measure of angle B 98 108?

We know that the sum of the internal angles of 1 triangle is always 180 degrees. Hence the sum of all the internal angles of the polygon is, 180 degrees x 4 triangles=720 degrees.=108 degrees.

### What is the sum of the measures of the central angles of a circle?

Sum of Central Angles: The sum of the measures of the central angles of a circle with no points in common is 360deg . For example, in the figure above, mPZR+mRZQ+mQZP=360deg .

**What seems to be the relationship between an inscribed angle and its intercepted arc? **

Theorem 70: The measure of an inscribed angle in a circle equals half the measure of its intercepted arc. The following two theorems directly follow from Theorem 70. Theorem 71: If two inscribed angles of a circle intercept the same arc or arcs of equal measure, then the inscribed angles have equal measure.

**What is the difference between minor and major arc? **

A minor arc refers to an arc that is smaller than a half circle. A central angle which is subtended by a minor arc has a measure less than 180deg. The major arc is the larger of these two arcs.
