a student said that m<1=80 degrees. what error did the student make

The error the student made is referring to an angle, m<1, being equal to 80 degrees. It is incorrect to assign a measurement or value to an angle without any given information or reference point.

The error the student made is stating that m<1 is equal to 80 degrees. In geometry, angle measures are typically represented by lowercase letters, such as α, β, or θ. The statement m<1=80 degrees should have been written as m∠1=80 degrees or simply ∠1=80 degrees.

To identify the error in the student's statement, we need some context about the given information or problem. However, based on the given statement, it seems like the error lies in the notation used by the student.

In geometry, angle measures are typically denoted by lowercase letters with a number or an apostrophe. For example, m<1 represents the measure of angle 1. So, if the student said m<1 = 80 degrees, it could be the correct notation.

However, if the intention was to state that angle 1 measures 80 degrees, then the error lies in the use of the notation. The correct statement would be something like: "Angle 1 measures 80 degrees," rather than using the m<1 notation.

Without further context or information, it's difficult to determine the exact nature of the error.
