Question

Can anyone please help me with this.

Answer 1

8.

Congruent angles means congruent sides. In other words, equiangular triangles are also equilateral triangles.

Answer 2

Explanation:

Givens

The triangle is equilateral. Given

<K = < M = 60 Property of an equilateral triangle.

IE = IE Reflexive property

Proof

• <IEK = <IEM = 90 Property of perpendicular
• <EIK = 180 - 60 - 90 All triangles have 180 degrees
• <EIK = 30 Subtraction
• <MIK = 180 - 60 - 90 All triangles have 180 degrees
• <MIK = 30 Subtraction
• <MIE = <KIE Both = 30 degrees
• IE = IE Reflexive property
• <IEK = <MEI Both are right angles.
• ΔMIK ≡ΔKIE ASA
